Adding a device to the configuration
Use the hardware catalog to add modules to the CPU. There are three types of modules:
● Signal boards (SB) provide just a few additional I/O points for the CPU. The SB is
installed on the front of the CPU.
● Signal modules (SM) provide additional digital or analog I/O points. These modules are
connected to the right side of the CPU.
● Communication modules (CM) provide an additional communication port (RS232 or
RS485) for the CPU. These modules are connected to the left side of the CPU.
To insert a module into the hardware configuration, select the module in the hardware
catalog and either double-click or drag the module to the highlighted slot.
