Frequently Asked Questions - AC1311 IFM

How to adjust the screen contrast?

Press simultaneously the right button and the ▲ button (too bright) or ▼ button (too dark) to change the contrast.

What does the lit PWR/COM LED indicate?

The PWR/COM LED lit indicates that AS-i power is present and at least one slave has been detected.

How to address a new AS-i slave?

In the Address Slave menu, select the option to re-address a connected slave or use automatic addressing (easy startup) to assign the next available address.

What is the required power supply voltage?

The controller requires a 24 V DC power supply (range: 20...30 V DC) connected to the +24V and 0V terminals.

How to navigate the menu?

Use the MENU button to open the main menu, then the ▲ and ▼ buttons to browse options. Press MENU to select.

What to do if the CONF/PF LED flashes?

A flashing CONF/PF LED indicates a peripheral fault on at least one connected slave. Check the slaves and their connections.

Can I use the device as a gateway?

Yes, the controller can operate in gateway mode to communicate with a higher-level control system. This mode is configurable in the PLC Setup menu.

How to update the firmware?

In the System Setup menu, select the firmware update option. A specific programming software is required.

What cables are needed for programming?

Use the E70320 programming cable to connect the controller to the host via the RS232C interface.

How to reset the controller to factory settings?

The manual does not specify a hardware reset. You can restore default settings via the menu if available, or contact IFM support.

CANopen Status LEDs (Network Status)

Function and features

• The controller _e (AC1311/AC1312) integrates one or two AS-i masters (both in accordance with the AS-i version 2.1), a mini controller and a CANopen interface
• 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 host: 20m
- Potential separation from the controller e power supply
- Programming cable E70320 for connection to host required

CANopen interface

• Baud rate 10k, 20k, 50k, 125k, 250k, 500k, 800k, 1Mbits/s
• Max. distance between controller _e and host: depending on the baud rate
• Potential separation from the controller _e power supply
• Up to 127 controllers connected in parallel
• Pin connection: Pin 1: V-; Pin 2: CAN_L; Pin 3: Shield; Pin 4: CAN_H; Pin 5: V+

Installation

Fix the controller _e onto a 35mm rail. 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 converters.

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 safe ground connection between AS-i controller _e (terminal FE) and ground of the unit.

Supply the CANopen controller _e with a 24V DC voltage (20...30V DC).

Connection is made to the terminals +24V and 0V.

Operating and indicating elements

Information concerning the state of the master (AC1311) / master AC1312) 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

CANopen status LEDs (module status)

• LED green flashes 1Hz: Pre-operational status
• LED green flashes 2Hz: Prepared status
• LED green lights: Operational status
• LED red flashes 1Hz: Initialisation error

CANopen status LEDs (network status)

• LED green flashes 1 Hz: BUS OFF
• LED green lights: Online, connection ok
• LED red flashes 1 Hz: Other faults

CANopen power

• LED green lights: Supply voltage on
• LED green is off: No voltage, controller

_e not initialised

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

Operation

To operate an AS-i system a special AS-i power supply is required. Connection is made to the terminals AS-i + and AS-i -.

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.

Menu overview

Open the main menu by pressing the left button "MENU" in the start display.

To navigate within a menu point press the button or .

Press the buttons simultaneously to switch between the German and English menu.
