11.PROGRAMMING DIGITAL INPUTS AND OUTPUTS
11.1.
The pico-PLC
The internal pico-PLC is used to connect the external world (inputs/outputs) with the world of the
parameters of the SLVD-N. The PLC can be used to copy digital input to a binary parameter, to copy a
binary parameter to a digital output and to execute mathematical and Boolean operations. The PLC
program must be inserted as a list of instructions by using the keyboard or by the serial line using a PC
and an interface program. A PLC program (see
Appendix F
) written to meet the needs of a large
number of applications corresponds to the default parameters (b99.12). In most cases it is not
necessary to program the PLC itself. The main features of the pico-PLC are:
