SmartRadar FlexLine Part No.: 4417.762_Rev07
6 - 6 Service Manual
NOTE: A protocol switch has been implemented as to switch
back and forward between the GPU-FlexConn and
the Modbus protocol.
The physical layers for the communication are RS-232, isolated and
non-isolated, and RS-485, isolated. RS-232 is used for direct point-to-
point connections whereas RS-485 facilitates a multi-point network with
up to 32 drivers and 32 receivers.
The HCI-GPU (slave) module can be used in any field devices provided
with the FlexConn architecture.
The Modbus protocols can be used when the SmartRadar FlexLine
interfaces to a DCS or SCADA system.
