13.4 Parameterising 1xcounter/16xdigital input module
13.4.1 Parameter data
l For the 1xcounter/16xdigital input, 3 bytes of parameter data are available.
The parameter data can be used to assign a mode to the internal counter
and to configure the digital input filter.
l The module can be parameterised with the configuration tool or via slot and
index.
– To set the parameters via slot and index, the function blocks SFB 52 (read)
and SFB 53 (write) are required. ( ¶ 10.5−3)
