Constants and connectors - Co

Constants and connectors (Co) represent inputs, outputs, flags and constant voltage levels
(constants).
Inputs:
1) Digital inputs
Digital inputs are identified with an I. The number of the digital inputs (I1, I2, ...) corresponds
to the number of the input connectors of the LOGO! Base Module and of the connected
digital modules, in the order of their installation. The fast digital inputs I3, I4, I5, and I6 of the
LOGO! versions LOGO! 24/24o, LOGO! 24C/24Co, LOGO! 12/24RC and LOGO! 12/24RCo
can be used as fast counters.
