Frequently Asked Questions - PlantVisorPRO Carel

What is the 'Smooth lines' function on the PlantVisorPRO?

The Smooth lines function keeps the installation temperature stable around the setpoint by modulating the expansion valve opening via a PID algorithm. This avoids frequent start/stop cycles and improves energy efficiency.

How to configure the 'Floating suction' function?

Go to the 'Energy' menu (PVPRO) or 'Add-ons' (BOSS) and select 'Suction pressure optimization'. Associate the installations with the rack, choose the mode (Smooth lines or Duty cycle), then define parameters such as min/max setpoints, gradient, and sampling interval.

Which controllers are compatible with the PlantVisorPRO?

The PlantVisorPRO is compatible with CAREL controllers such as MPXPRO (versions ≥3.2 for Smooth lines), MPXone, IR33, and other models using the Modbus protocol.

How to associate installations with a rack?

In the 'Association' tab, double-click on the desired rack, select the devices in the left list, check 'Smooth lines function' if applicable, then click the right arrow and save.

What do the colors (green, yellow, orange, red) in the interface mean?

These colors indicate the status of installations: green = optimal operation (pressure increase margin), yellow = warning, orange = critical, red = overloaded. The plugin adjusts the suction pressure based on the number of installations of each color.

What is the difference between 'Smooth lines' and 'Duty cycle' modes?

Smooth lines uses a PID algorithm to continuously modulate the expansion valve, while Duty cycle is based on the percentage of ON/OFF operating time of the installations. Smooth lines offers finer and more stable regulation.

How to reset the default suction pressure setpoint?

In the 'Parameters' tab of the plugin, you can set the minimum and maximum setpoint values. To reset, disable and re-enable the plugin, or manually set the default values via the supervisor.

What to do if an installation is marked 'offline' or 'N/A'?

Check the network connection and power supply of the installation. If offline, the plugin may consider the installation as yellow/orange/red depending on duration. For installations without Smooth lines (N/A), the setpoint will not be increased.

How to update the firmware of the PlantVisorPRO?

The update is done via the supervisor. Refer to the manual for detailed procedure. Generally, download the update file and use the supervision tool to transfer it to the module.

Where can I download the full manual?

You can download the manual in PDF format for free on notice-facile.com or on the official CAREL website. The manual is available in French, English, German, Spanish, and Italian.

1.1 Smooth lines: how it works

The main target of the Smooth lines function is to keep the control temperature very stable around the set point, avoiding frequent ON/OFF cooling request cycles, controlling the valve by changing the superheat set point (P3). The parameters involved in the Smooth lines configuration are listed in the following table:

Parameter	Menu Description	Visibility
St CtL Control set point Supervisor & user interface
rd CtL Control differential Supervisor & user interface
P3 Eud Superheat set point Supervisor & user interface
PHS Eud Positive SH off set Supervisor, UI, Applica
PLt	Eud	Offset below set point for cut-off	Supervisor, UI, Applica
PSI	Eud Integral time Supervisor, UI, Applica
PSM	Eud Enable function Supervisor, UI, Applica
PSP	Eud	Proportional coefficient	Supervisor, UI, Applica
PSd	-	Derivative time	Supervisor
TSH	-	Superheat threshold	Supervisor
FSt	-	Superheat averaging time window	Supervisor

Tab. 1.a

The function operates as follows: when the control temperature reaches the set point, the refrigeration cycle is not stopped, rather the expansion valve opening is modulated. Modulation is achieved by changing the superheat set point based on a specific PID algorithm. The calculated superheat set point will be between the values P3 and P3+PHS, and consequently the valve will open or close based on the required control temperature, while staying close to the set point.

The algorithm remains active until the control temperature falls below the threshold St-PLt; control in any case stops below this threshold.

When the Smooth lines function is enabled, a variable tells the supervisor whether the MPXPRO (MPXPRO/MPXone Medium + EVDice/mini and MPXone Advanced) is operating with a certain margin, i.e., the suction pressure set point on the corresponding line can be increased without jeopardising control. In detail, superheat set point is higher than P3 + THS. The average is calculated inside the time window FSt.

Fig. 1.b

1.2 Smooth lines on MPXone\* MPXpro: configuration

Smooth lines is available on MPXone* and on MPXPRO from version 3.2 and higher.

The Smooth lines configuration parameters are listed in Table 1a.

The basic settings are listed below, with the parameter name and default value:

1. enable function, default value is PSM = 0 (disabled);

2. set maximum superheat off set, default value is PHS = 15 (K).

This parameter prevents the calculated superheat set point from rising too high

1. set compressor cut-off offset, default value is PL t = 2 (K).

This parameter prevents the control temperature from dropping too far below the set point, stopping the cooling request when the temperature falls below this safety threshold.

1. set main control differential, default value is rd = 2 (K);

if smooth lines is enabled, the suggested value is rd = 4 (K).

1.3 Floating suction on pRack

The pRack application features the Floating suction function, allowing the supervisor (PVPRO/Boss) plug-in to increase the suction pressure set point when the unit operating conditions are favourable. In practice, the supervisor, by monitoring the units connected to the rack, verifies that these are able to reach the set temperatures, and only in this case enables the rack to increase the suction pressure. Increasing the suction set point allows the system to operate more efficiently, wasting less energy.

The configuration path is as follows :

graph TD
    A["C. Compressors"] --> B["a. Line 1"]
    B --> C["d. Energy saving"]

Fig. 1.c

This path refers to suction Line 1, Line 2 is configured in the same way. If the rack manages one suction line only, the path will be: C.Compressors → d.Energy saving

Once having entered the configuration menu, screen Cad08 is used to enable the Floating suction function.

• Screen Cad09 defines the range in which the set point can be changed by the Floating suction plug-in.
• Screen Cad10 defines the maximum variation for increasing or decreasing the set point for each request from the plug-in, and the time it takes for the rack to decrease the set point if communication with the supervisor is lost.
• Screen Cad10a defines which communication port on pRack is used for the supervisor.

1.4 Floating suction on the supervisor

The PVPRO and Boss supervisors include the Floating suction function, which can be enabled and configured via a special menu. The supervisor must be able to identify which units are connected to the specific rack, so as to monitor them and safely enable the increase in the suction set point

On the PVPRO supervisor, this can be activated by clicking "Suction Pressure Optimisation" in the "Energy" menu.

Fig. 1.h

On the Boss supervisor, select "Suction Pressure Optimisation" from the Add-ons menu on the left side of the screen.

The "fl oating suction" algorithm can be used both on units with the Smooth lines algorithm or without this function (e.g. IR33, MPXPRO version < 3.2). If all of the units have the Smooth lines function available and activated, the algorithm can be optimised by checking a specific flag in the plug-in.

For devices that do not manage the "Smooth lines" function, the supervisor can estimate whether the cooling capacity delivered is adequate, evaluating the ON/OFF times for each unit (Duty cycle mode).

This guideline helps choose the most suitable option:

These two screens are displayed differently, depending on whether the associated units feature the Smooth lines function, i.e., whether or not the association has been created with the Smooth lines flag checked (see paragraph 2.2 for details).

If the units are not equipped with the Smooth lines function, or no association with the Smooth lines function has been created, the plug-in will work in "duty cycle" mode.

The following chapters show the details and configuration of the plug-in, based on the mode activated, Smooth lines or Duty cycle.

The plug-in settings can be changed in the "Parameters" tab, in turn divided into two main tabs:

Configuration

The configuration section shows the values of the parameters set on pRack. The following can be set here:

• the minimum and maximum rack working set point, within which the plug-in will calculate the optimal set point.
  • The gradient between set point increase/decrease steps
  • The time interval between samples (minimum time 10 minutes)
• The maximum number of units, divided by colour (operating conditions), for which the plug-in will calculate the rack set point

Units

The units section shows the list of devices associated with the rack and involved in the calculation of the optimal set point, the line they belong to and the corresponding serial address.

This screen can be used to set parameter TSH (default 2K), the offset to be added to parameter P3 (superheat set point).

There are four thresholds, associated with different colours, referring to device operating conditions:

• Green
• Yellow
• Orange
• Red

The first colour, green, indicates units where the average set point value is higher than P3 + TSH; this means the suction pressure set point can be increased. The status (colour) of the units is evaluated after each sampling interval. The rules that define monitoring are illustrated in Figure 2.f. The following table shows the criteria followed to adjust the rack set point based on the number of units with the same colour:

When the Smooth lines flag is checked, any units that are either offline or do not feature the Smooth lines function but that are in any case associated with the plug-in, are managed specifically.

If a unit is not available (offline) after the sampling time, this will be shown in black and considered unavailable for the pressure set point increase. This unit is considered as if it were yellow, orange or red, depending on how many times it has been declared offline.

If a unit without Smooth lines is associated with the plug-in, the supervisor will not monitor its operating conditions and will show it as N/A (not available). As the increase in rack suction pressure can affect the behaviour of the unit, the plug-in will restore the set point to the minimum value. These two specific scenarios are illustrated in Figure 2.g.

graph LR
    A["Yellow"] -->|A| B["Orange"]
    B -->|→| C["Red"]

if a unit is shown as N/A, it means it doesn't feature the Smooth lines function and any increases in the set point will be reset.

2.5 Operating details with Smooth lines

The "Details" tab offers users a detailed review, divided into four groups, of the plug-in configuration and operating status.

The "information" section shows a summary of the settings, both relating to the supervisor and the pRack, in particular:

• The time of the last sampling performed by the plug-in;
• The set point corresponding to the last sampling;
• A summary of the current configuration.

The plug-in settings can be changed in the "Parameters" tab, in turn divided into two main tabs:

Configuration

The configuration section is divided into two parts; the first is used to set some parameters relating to the pRack, such as:

• the minimum and maximum rack working set point, within which the plug-in will calculate the optimal set point.
  • the gradient between set point increase/decrease steps
  • the time interval between samples (minimum time 10 minutes)

The second part is used to set the parameters relating to the plug-in, such as:

• Time frame for calculating the Duty Cycle
• Frequency for calculating the Duty Cycle
• Percentage of maximum connection failure time
• Maximum number of units not connected

Units

The units section shows the list of devices associated with the rack and involved in the calculation of the optimal set point, the line they belong to and the corresponding serial address.

This screen is used to set the cabinet operating percentage, which by default is set to 70%

CAREL

In this case, as the units do not feature smooth lines logic, the plug-in checks the cabinet activation percentage over a specified period of time. If the operating percentage measured is greater than the set threshold, it is assumed that the cabinet has no operating margin and consequently the rack suction pressure set point cannot be increased. The threshold is defined by entering a percentage for each unit in the "Maximum Duty Cycle" column.

The following table shows the meaning of the settings and the corresponding default values.

Parameter Description Default value

Time frame for calculating the DC T	The unit duty cycle will be calculated within this time frame. The value can range from 10 to 180 minutes.	120 minutes
Frequency for calculating the DC Th	This specifies the frequency of the potential action on the set point: at the end of each period, the calculated duty cycle will be compared against the threshold for increasing or decreasing the set point. The value can range from 10 to 180 minutes.	30 minutes
Maximum connection failure time M	Maximum percentage of failed measurements for each unit associated with the rack. If this value is exceeded, the unit is considered off line.	30%
Maximum number of units not connected	If the number of off line units exceeds this number, the suction pressure set point will not be changed.	3

Tab. 1.a

2.7 Operating details (without Smooth lines)

The "Details" tab offers users a summary of the plug-in configuration and operating status.

The "information" section shows a summary of the settings, such as:

• the minimum and maximum rack working set point, within which the plug-in will calculate the optimal set point.
  • The gradient between set point increase/decrease steps
  • the time interval between samples (minimum time 10 minutes)
  • Sampling frequency
  • Number of configured devices
  • Maximum number of offline devices and percentage of cycle time before considering units offline (above which the rack set point is decreased)

The "Units" tab offers an overview of the instant operating status, the current, minimum and maximum duty cycle and shows which units are decreasing the rack set point.
