9.5.5 Data transfer of machine parameters > PLC
Up to 192 machine parameters are reserved for data transfer to the PLC. The
iTNC saves the contents of MP4210.x, MP4220.x and MP4310.x in PLC
words. You must call the contents of MP4230.x and MP4231.x by using
Module 9032. In these machine parameters you can save, for example, values
for PLC positioning or datum shifts, feed rates for PLC positioning or coding
for the release of certain PLC functions. The number of indexes for MP4230.x
can be increased to a maximum of 99 with the NUMBERMP4230 = entry in
OEM.SYS. No entry or an invalid entry defines 32 indexes for MP4230.x. You
must evaluate the transferred numerical values in your PLC program. The iTNC
internally rounds input values less than 0.001 mm (or °) to 0.001 mm (or °).
