Frequently Asked Questions - AC1356 IFM

How to power the AC1356 controller?

Power with 24 V DC (20...30 V SELV) via terminals +24 V and 0 V. Preferably use IFM power supply DN2011. Never connect negative potentials to each other or to earth.

How to connect the RS232C programming cable?

Use cable E70320 between the controller's RS232C port and the PC. The maximum distance is 20 m. The baud rate is set from 4800 to 115200 baud in the 'System Setup' menu.

What do the LEDs on the front panel mean?

PWR/COM on: AS-i power present, at least one slave detected. PROJ on: project mode. CONF/PF on: configuration error. ETH NET: Ethernet data exchange. PROFIBUS on: Profibus bus error.

How to perform a 'Teach in' of the AS-i configuration?

In the main menu, select 'Quick Setup' or 'Master Setup' then 'Teach in'. This projects the current configuration of detected AS-i slaves.

How to switch to protected mode?

In 'Master Setup', select 'Switch to protected mode'. The controller then monitors the configuration. If a slave with address 0 is present, the PROJ LED flashes and the switch is impossible.

How to reset a forgotten password?

Enter the password CE01 to return to user mode. The password is saved even after power-off via 'Store System'.

What is the function of the Profibus DP interface?

The Profibus DP interface allows connecting the controller to a higher-level fieldbus. Baud rate from 9600 baud to 12 Mbaud. Up to 31 controllers in parallel per segment. Connection pin 3 (signal B) and pin 8 (signal A).

How to adjust the screen contrast?

Press simultaneously the right button and the up button (too bright) or down button (too dark) to adjust.

Can I use a standard 24 V power supply?

Yes, but it must be galvanically isolated and protected by a UL fuse of 5 A max (0...20 Veff) or 100 Vpeak (20...30 Veff). Standard switching power supplies can disturb AS-i signals.

How to troubleshoot a flashing PROJ LED?

A flashing PROJ LED indicates that a slave with address 0 is connected. This slave must be addressed via 'Address Slave' or removed to switch to protected mode.

USER MANUAL AC1356 IFM

Function and features

• The controller e integrates one or two AS-i masters (AC1355/AC1356, both in accordance with the AS-i version 3.0), a mini controller, an Ethernet interface and a Profibus DP 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 PC: 20 m
• Potential separation from the controller _e power supply
• Programming cable E70320 for connection to PC required

Ethernet programming interface

• 10 Mbps and 100 Mbps
• TCP/IP - Transport Control Protocol/ Internet Protocol
  Modbus TCP (only as diagnostic interface) The outputs are not reset when the connections are disconnected (no watchdog function)
• UDP - User Datagram Protocol
• Support of the CoDeSys programming functions and the global network variables
• RJ45, Twisted-Pair

Profibus-DP interface

• baud rate 9600 baud to 12 MBit/s
• 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 DIN 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 safe ground connection between AS-i controller (terminal FE) and ground connection of the unit.

Supply the controller 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 (AC1355)/masters /AC1356) 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 ETH NET: Exchange of data via the Ethernet interface
• 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.
