Master to Master EtherCat communication

GOAL: I am trying to exchange 3 variables between TwinCat primary master device, and ctrlX core as secondary master device. Structure is 2 variables of the same type, and 1 variable of a different type.

WORKING: I am able to exchange a single input and single output between devices for types BYTE; WORD; INT; REAL and BIT8.

PROBLEMS:

  • Using the BOOL type variable as input or output results in an error (as attached) on ctrlX device - stuck in Pre-OP
  • Adding a 2nd input or output of any type results in an error (as attached) on ctrlX device - stuck in Pre-OP

Topology image attached and using ctrlX version 1.12.7

Is there a setting or similar I need to use to enable using more than 1 input and output?
