Actual posi-
tion
The firmware version V3.8 of the FM 353 positioning module in
conjunction with the blocks of the “FM353_354” block library pro-
vides direct access to the actual value. This is stored in the
checkback signals during the module cycle (2 ms) and read by
the POS_CTRL block. In addition, as previously, the actual value
is included as a DINT variable in the basic operating data read
request.
