Interfaces
6.3.5.1 Basic equipment of mainboard
The mainboard is available in two versions: Standard and Extended
The following interfaces are provided:
● 1 Ethernet interface (Modbus TCP) for the Standard variant
2 Ethernet interfaces (Modbus TCP) for the Extended variant
● 3 RS485 interfaces (Modbus RTU / ASCII)
● 1 RS232 interface, for firmware updates
6.3.5.2 I/O module definition
Analog module type 1 (2AI/2AO)
● Two analog inputs, switchable as voltage input or 4 ... 20 mA current input
● The first analog input also has a serial HART master interface
● Two analog outputs (4 ... 20 mA)
● The first analog input also has a serial HART slave interface which can be optionally
configured as HART master.
● Two electrically isolated auxiliary voltages for supplying up to two current loops; the
module can be operated both passively and actively with two auxiliary voltages per
module
Analog module type 2 (2AO)
● Two analog outputs 4 ... 20 mA
● The first analog output also has a serial HART slave interface which can be optionally
configured as HART master.
● Two electrically isolated auxiliary voltages for supplying up to two current loops; the
module can be operated both passively and actively with two auxiliary voltages per
module
Digital module type 1
● Two switching outputs, individually switchable as digital input
● 4 digital outputs, one of which can be used as frequency output
Interface module FOUNDATION Fieldbus (FF)
● One serial FOUNDATION Fieldbus Slave interface
Detailed descriptions of the MODBUS, HART and FOUNDATION Fieldbus
protocols are available as separate documents on the product CD, at
www.sick.de or from SICK Service.
