Programmer Connections in a Multidrop Network

In a multidrop network, a programmer connected to the CPU can communicate with the Remote I/O Scanner over the serial link, as shown below. A programmer can also be connected directly at the remote drop. However, when the Remote I/O Scanner is part of a multidrop network, its serial port, which is used for connection of the serial link, is not available for direct connection of a programmer.

The illustrations that follow suggest how extra connectors may be installed to allow the use of a programmer at various points in the system, without disturbing the serial link between the PLC and the remote drop. When extra connectors are used, it is important to be sure that the connections will be secure. For example, the connectors can be permanently mounted on panels.

The illustrations show connections for a WorkmastertII programmer, although a different type of programmer could be used.

If the programmer does not have a Workstation Interface card, RS232±to±RS422 conversion must be provided at each location. A conversion box can be installed at each drop, or one conversion box can be moved from location to location with the programmer.

In locations where isolation is not a problem, the non±isolated RS232±to±RS422 Conversion Box (IC690ACC900) can be used.

In locations where ground potential differences may occur, it is important to provide adequate ground isolation. Repeater/Converter Box (IC655CMM590) that provides both RS232±to±RS422 conversion and isolation should be used.
