The following interfaces are available for the FIDOR:
● Ethernet
● CAN
Option: RS485/422 (Modbus RTU) via the CAN bus plug
● Analog and digital interfaces (depending on version).
The analog and digital interfaces are part of the GMS800 I/O module. The GMS800 I/O
module can be optionally installed in the rear cover of the 19"enclosure or be con-
nected externally using the CAN bus.
 Operating Instructions “GMS800 I/O Module”
The parameters of the GMS800 I/O module are set with SOPAS ET or the BCU user
interface.
2.4 Remote control
2.4.1 Ethernet
Protocol:
● Modbus TCP/IP.
Operation via SOPAS ET (option)
Operator menus and measured value displays are also available on an external PC via Eth-
ernet for user comfort (with the engineering tool SOPAS ET  Operating Instructions
“SCU”).
2.4.2 Modbus
Modbus
®
is a communication standard for digital controls to connect a »Master« device
with several »Slave« devices. The Modbus protocol defines the communication commands
only but not their electronic transfer; therefore it can be used with different digital inter-
faces (for FIDOR: Ethernet).
