The HEDA option (option M10 or M11) can be used to send 4 process values in the
"HEDA standard" operating mode from master to slave. A return transmission from
Slave to Master is possible with "HEDA advanced".
First choose, if Compax3 is HEDA Master or HEDA Slave:
 HEDA master: in order to send process values
 HEDA slave: in order to receive process values
Please respect that only 1 HEDA station can be Master.
 Error reaction (from Compax3) at bus failure:
 activated: Compax3 switches to error state in the case of a bus error. (Error
reaction 2: Downramp / apply brake / de-energize.)
 deactivated: Compax3 will ignore a bus error.
