The Programmable Logic Controller Gateway provides a method of economically connecting various Programmable Logic Controllers to your Honeywell TotalPlant Solution (TPS) system .

The PLCG runs under an unmodified HG (Hiway Gateway) software personality . The hardware is similar to HG hardware, contained in a standard TPS five-slot equipment module that supports the Local Control Network (LCN).

The baud rate of the two serial interfaces serving Ports 1 and 2 are set-up with the jumpers on TS2. See Table on the PLCI board for the pinning information . Be sure the baud rate for a given port matches the PLC(s) it is communicating with . The baud rates of the ports may be set at different speeds . Notice Port I uses the higher-numbered pins .

The transmit and receive data parity for Ports I and 2 are set by jumpers 5 and I , respectively . To send and receive odd parity on a port, its respective jumper must be shorted. Conversely, even parity is obtained by the jumper being open . Make sure the parity of a port agrees with the parity sent and expected by the PLC(s) to which it is connected.
