AC1325 - Industrial Automation IFM - Free user manual and instructions

USER MANUAL AC1325 IFM

• The AS-i DP gateway integrates one or two AS-i masters (AC1325/AC1326, both in accordance with the AS-i version 2.1) and a Profibus DP interface

• It controls the exchange of data to the sensor/actuator level

• communicates with the higher control level (in the gateway mode) Interface RS232C The serial interface cannot be used. Profibus-DP interface

• Baud rate 9600 to 12MBaud

• Max. distance between gateway and host: depending on the baud rate

• Potential separation from the gateway power supply

• Up to 31 gateways connected in parallel

• Pin connection: pin 3: signal B, pin 8: signal A Installation Fix the AS-i DP gateway 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 inverters. Electrical connection Disconnect the installation from power. Connect the unit as indi- cated 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 DP gateway (terminal FE) and ground of the unit. PAGE 9Supply the AS-i DP gateway with a 24V DC voltage (20 ... 30V PELV), e.g. from the 24V power supply DN2011 of ifm electronic. The connection is made to the terminals +24V and 0V. Operating and indicating elements Information concerning the state of the master (AC1325)/masters /AC1326) and the connected system is given via three diagnostic LEDs on the AS-i DP gateway.

• 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

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 AS-i DP gateway. 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. PAGE 12
