Logicmaster 90-30/20/Micro programming software is part of a family of products used to configure and program the full line of Series 90-30, Series 90-20, and Micro programmable controllers. Configuration is the process of assigning logical addresses, as well as other characteristics, to the hardware modules in the system. It may be done either before or after programming, using the configuration software; however, it is recommended that configuration be done first. Programming consists of creating an application program for a PLC. Because Series 90-30 PLCs, Series 90-20 PLCs, and Micro PLCs have a common instruction set, all can be programmed using this software.
