- The controller _e integrates one or two AS-i masters (AC1027/AC1028, both in accordance with the AS-i version 2.1), a mini controller and a Profibus DP interface.
The Profibus DP interface is compatible with the Profibus DP interface of the AS-i controllers AC1005/AC1006. It must be configured using the file "ifm300AB.gsd".
- 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)
PLC programs of the controllers AC1005/AC1006 for signal pre-processing with Asisys must be converted for AC1027/AC1028 and CoDeSys.
- 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: 20 m
- Potential separation from the controller e power supply
- Programming cable E70320 for connection to host required
Profibus-DP interface
• Baud rate 9600 to 12 MBaud
- Max. distance between controller e and host: 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. 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 (AC1027)/masters/AC1028) 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

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.
