1.1.2.
Special functions of binary inputs of module CP-1004
Besides the function of ordinary inputs, the binary inputs DI0, DI1 (counter 1) and DI2, DI3 (counter 2)
can be
set to one of special functions that allow the connection of an incremental position scanner,
application of fast counters, period and phase shift measurement (e.g. for generator phasing), etc. The
functions are described in detail in the manual Programmable controllers Tecomat Foxtrot,
TXV xxx xx
,
where the functions are in tables together with concrete connection examples.
