Ethernet settings
For data communication, connections via Ethernet are mainly used. Go to parameter branch:
GasLab Q2 – Basic system – I/O – Board 0: CPU. Fill in your changes, proceed like explained in the
online help.
Serial interface RS485
These connections include, for example, other measuring instruments, devices for final processing
and evaluation, PLC systems, etc. Go to parameter branch GasLab Q2 – Basic system – I/O – Board
0: CPU. On the “Parameters” tab: Set the type of CH1 (terminals TB4-1 to TB4_3) or CH2 (terminals
TB4-4 to TB4-6) from “Unused” to “Protocol channel”.
Digital inputs
There are two electrically isolated inputs supplied by the device. Go to parameter branch GasLab
Q2 - Basic system – I/O – Input channels and set the type from “Unused” to “Message input” or
“LF pulse input”.
Digital outputs
There are two outputs (electrically isolated passive output circuits). Go to parameter branch
proChain GC – Basic system – I/O – Output channels set the type from “Unused” to to the desired
function offered in the pop-up menu e.g. “Message output” or “Pulse output”.
Analog outputs
Four common galvanically isolated active output circuits ("common ground" / short-circuit proof)
with 0 or 4 to. 20 mA are available. Go to the parameter branch "GasLab Q2 – basic system I/O -
output channels "and set in the register card the type of current output for the relevant channel (in
the range I1+ I-, I2+ I-, I3+ I- or I4+ I-). For the Current Range parameter, set the desired current
output range: - 0 to 20 mA or 4 to 20 mA.
