Frequently Asked Questions - AC1355 IFM

How to connect the controller to a PC?

Use the programming cable E70320 on the RS232C interface. The maximum distance is 20 meters. You can also use the Ethernet interface (RJ45) with TCP/IP.

What is the required power supply?

The controller requires a 24 V DC (20...30 V) SELV power supply with galvanic isolation and a UL fuse (5 A max for 0...20 Veff or 100/Vpeak for 20...30 Veff). Use a specific AS-i power supply like the ifm DN2011.

How to adjust the screen contrast?

Press simultaneously the right button and the up button (to lighten) or down button (to darken) to adjust the contrast.

What do the LEDs on the front panel mean?

PWR/COM: AS-i power present and at least one slave detected (solid) or no slave (blinking). PROJ: project mode (solid) or unable to switch to protected mode (blinking). CONF/PF: configuration fault (solid) or periphery fault (blinking). ETH NET: Ethernet data exchange. PROFIBUS: Profibus bus error.

How to change the menu language?

Press simultaneously the two navigation buttons (up and down) to toggle between German and English.

How to reset to factory settings?

Go to the 'System Setup' menu and select 'Factory reset'. Warning: this erases all customized settings.

What is the maximum number of AS-i slaves supported?

The AC1355 controller has one AS-i master and can handle up to 31 slaves per master (addresses 1 to 31).

How to program the controller?

Use the CoDeSys software. Connect via the RS232C interface (cable E70320) or Ethernet. Network global variables and CoDeSys functions are compatible.

What is the default password for user mode?

The default password to reactivate user mode is 'CE01'. Enter an invalid password (e.g. 1000) to lock the settings.

Can I use a standard 24 V power supply?

No, a specific AS-i power supply (e.g. AC1216) is necessary because standard switching power supplies suppress AS-i data signals. The AS-i power supply ensures data decoupling.

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 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 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 _e (terminal FE) and ground connection 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 (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.
