4.13.3 External Control Interface Connection
Communication between the external controller and the GTIB-30 must occur via
standard Modbus protocol using either RS485 or RS232. Certain parameters will
need to be set on the GTIB-30 to enable correct communication with different control
systems. Contact PPS to ensure compatibility with your external control system.
The external control needs to be connected to the RS485 connector for RS485
operation; for RS232 operation, either of the RS232 connections can be used. These
connections are shown in Figure 33, Figure 34, Figure 35, and Figure 36.
