Frequently Asked Questions - AC1366 IFM

How to power the AC1366 controller?

Connect a 24 V DC power supply (20...30 V PELV) to the +24 V and 0 V terminals. The power supply must be galvanically isolated and protected by a UL listed fuse of max 5 A (for 0-20 V) or 100 V peak (for 20-30 V).

What do the LEDs on the front panel mean?

PWR/COM on = AS-i power present and at least one slave detected. PROJ on = project mode active. CONF/PF on = configuration fault. PROFIBUS on = Profibus bus error. RUN (if present) = PLC running.

How to configure AS-i slaves?

Use the 'Address Slave' menu to re-address a slave or enable automatic addressing (easy startup). In 'Master Setup', switch to project mode to modify the configuration.

How to adjust the screen contrast?

Press simultaneously the right button and the ▲ button (to increase) or ▼ button (to decrease) until the desired contrast is obtained.

What is the maximum distance for the RS232C interface?

The distance between the controller and the PC must not exceed 20 meters. Use the E70320 programming cable.

How to connect the controller to the Profibus-DP bus?

Connect signals A (pin 8) and B (pin 3) of the Profibus connector. The baud rate can range from 9600 baud to 12 Mbaud. Up to 31 controllers can be connected per segment.

What to do if no AS-i slave is detected?

Check the AS-i power (LED PWR/COM should be on or flashing). Ensure the slaves are properly wired and their addresses are valid (no address 0 in protected mode).

How to update the firmware?

In the 'System Setup' menu, select 'Update Firmware'. Specific programming software is required. Contact IFM support to obtain the files.

Can the device be used as a gateway without a PLC?

Yes. In the 'PLC Setup' menu, disable the gateway mode to not use the integrated PLC. The controller will then function only as a gateway between AS-i and the fieldbus.

What are the recommended installation conditions?

Mount the device on a 35 mm DIN rail in a protected electrical cabinet (IP20). Avoid condensation, excessive dust, vibrations, and shocks. Do not mount near frequency converters.

Function and features

• The controller _e integrates one or two AS-i masters (AC1365/AC1366, both in accordance with the AS-i version 3.0), a mini controller and a Profibus DP interface (optional)
• It controls the exchange of data to the sensor/actuator level
• processes the peripheral data in the integrated processor (signal preprocessing)
• works as stand-alone controller with exchange of data to the PC (visualisation)
• communicates with the higher control level (in the gateway mode)

Programming interface RS232C

• Baud rate 4800 to 115,200 baud
- Max. distance between controller e and PC: 20 m
- Potential separation from the controller e power supply
- Programming cable E70320 for connection to PC required

Profibus-DP interface

• Baud rate 9600 to 12 MBaud
- Max. distance between controller e and DP master: depending on the baud rate
- Potential separation from the controller e power supply
- Up to 31 controllers connected in parallel per segment
- Pin connection: pin 3: signal B, pin 8: signal A

Installation

Fix the controller _e onto a 35 mm rail which has an electrically safe ground connection. The protection rating of the unit is IP20, therefore it should be mounted in a protected location (e.g. control cabinet).

Ensure a condensation-free environment. Avoid excessive dust, vibration and shock. The air circulation through the vents must not be impeded.

Avoid installation in direct vicinity of frequency inverters.

Electrical connection

Disconnect the installation from power. Connect the unit as indicated on the terminals. Never connect the minus potentials to each other or the minus potentials to the FE connection. Ensure an electrically save ground connection between AS-i controller _e (terminal FE) and ground of the unit.

Supply the controller _e with a 24 V DC voltage (20...30 V PELV), e.g. from the 24 V power supply DN2011 of ifm electronic. The connection is made to the terminals +24 V and 0 V.

Operating and indicating elements

Information concerning the state of the master (AC1365)/masters/AC1366) and the connected system is given via three diagnostic LEDs on the controller _e .

• LED PWR/COM lights: AS-i voltage present, at least one slave was detected
• LED PWR/COM flashes: AS-i voltage present, but no slave was detected correctly
• LED PROJ lights: Projection mode active, the configuration monitoring is deactivated
• LED PROJ flashes: Projection mode active, changeover to protected mode not possible as a slave with the address 0 is connected
• LED CONF/PF lights: Projected and current configuration do not match
• LED CONF/PF flashes: Periphery fault on at least one connected slave
  • LED PROFIBUS lights: Bus error Profibus DP

Contrast setting

The contrast can be directly changed by simultaneously pressing the right button and the -button (too bright) or the -button (too dark).

increase contrast

decrease contrast

Operation

To operate an AS-i system a special AS-i power supply is required (e.g. AC1216). The AS-i power supply supplies the yellow AS-i cable with energy and implements a data decoupling to the voltage regulator of the power supply. Standard switched-mode power supplies would consider the AS-i data signals as interference signals and suppress them.

Disconnect the power supply before connecting the controller _e .

The AS-i system is operated ungrounded. AS-i + and AS-i - are to be symmetrical to the ground potential of the installation. Ensure a low resistance connection of the symmetry point of the AS-i power supply (terminal shield) to the ground of the installation.
