Cyclic channel. Read-only variables for the CNC-PLC
The plc.m.p. SRR700 (P28) through SRR739 (P67) indicate which drive and what type of information
will be placed in CNC registers R700 through R739.
These parameters are set in 1.5 format. The units digit identifies the drive (node) supplying the data
and the decimals indicate the identifier number (see table below).
For example, "P32=1.00040" indicates that PLC register R704 contains the "VelocityFeedback"
supplied by the drive located in bus node 1.
The type of information available and its associated identifiers are:
The bits of identifier 33172 "FagorDiagnostics" contain the following information:
P28=>R700 P29=>R701 P30=>R702 P31=>R703 etc.
To identify the units of the variables, see the drive manual.
Read-only registers R700 through R739 are updated at the beginning of the PLC
scan, unless the MRD instruction is used.
