Programming the FM 350-1
5
Chapter Overview
This chapter contains all the information necessary for programming the FM 350-1 in the
S7-300. For linking the FM 350-1 into a user program, you are provided with STEP 7 blocks
that make handling the desired functions easy for you.
Table 5- 1 Blocks that are described in this chapter
Block number Block name Meaning
FC 2 CNT_CTL1 Controlling of the FM 350-1
FC 3 CNT_CTL2 Controlling of the FM 350-1
(only in isochronous mode)
FC 1 DIAG_INF Read Diagnostics data record 1 from the FM 350-1
Use of the blocks is illustrated in an example program. The example program shows block
calls and contains the necessary data block.
You can also operate the FM 350-1 without FCs, in which case you control and monitor the
FM 350-1 via the control and feedback interface.
