The digital MODBUS services (coil services) are bit accesses, with which only the

states of digital I/O modules can be determined or changed. Complex I/O

modules are not attainable with these services and so they are ignored. Because

of this the addressing of the digital channels begins again with 0, so that the

MODBUS address is always identical to the channel number, (i.e. the digital input

no. 47 has the MODBUS address "46").
