Description
SIMATIC S5-115U CPU 942 central processing unit, built on a 16-bit processor operating from the internal 24 V DC / 5 V logic supply. It executes the STEP 5 instruction set (binary, digital, and floating-point operations) with integral RAM/EPROM program memory and a serial programmer (PG) interface. The 942 is a mid-range 115U processor supporting both centralized and distributed I/O configurations with up to three expansion units. In this panel it is deployed in Racks 01 and 02 as the paired control processors of the Seawater Screen Control system.
