3.8.9.2 External Parameters E40xxx
128 words x 32 bits are addressed by E40000 to E40127.
Parameters E400xx are written by the user programme. They are used to include signed numerical values which can
be dimensions, offset, etc. for use in the in the part programme.

3.8.9.3 Parameters E42xxx
128 words addressed from E42000 to E42127. These parameters can be read from and written to by the user
programme (functions R_E42000 (..) and W_E42000 (..)) and by the part programme. They are accessible for read
and write using dynamic operators.
REMARK There is no guarantee of coherence of the exchanges at system level (for instance,
read by the machine processor can be interrupted by write by the CNC processor).
It is therefore up to the user to provide a secure exchange mechanism.
