V-Memory Block Read; Block Read Data: Plc Module - Siemens SIMATIC 505 User & Programmers Manual

2.6 Block Read Data: PLC
2-12 Software Interface
Module
The module performs a block read of 300 consecutive V-memory locations
starting at the V-memory location specified by WY5. See Figure 2-3.
Table 2-8 contains all the information necessary for the module to perform a
complete machine cycle, if so instructed.
Profile data consists of 5 sets of 44 values, followed by 5 hold values. The
44-value sets correspond to the 5 machine functions.
