    About this Manual: The SRM1 is a special CompoBus/S controller that provides remote I/O with greatly reduced wiring. A distributed I/O system with up to 32 Slaves and 256 I/O points can be constructed. There are two manuals describing the setup and operation of the SRM1: The SRM1(-V2) Operation Manual (this manual) and the CPM1/CPM1A/CPM2A/CPM2C/SRM1(-V2) Programming Manual (W353).
