The Rx PDO contains the input data used to control the outputs (I/O.0 and I/O.1)
depending on the encoder value.
Byte Assignment
0 Comparison value (LOW byte) Bits 0 ... 7
Selection of comparison value 1 Comparison value (MID byte) Bits 0 ... 7
2 Comparison value (HIGH byte) Bits 0 ... 7
3 Reserved
4 Control Bits 0 ... 1 Setpoint selection
00: No setpoint selection
01: Setpoint selection for output I/O.0
10: Setpoint selection for output I/O.1
11: Setpoint selection for outputs I/O.0 and I/O.1
Bit 2 Reserved
Bit 3 Condition for setting the output = HIGH
0: If SSI encoder value is higher than setpoint
1: If SSI encoder value is lower than setpoint
Bits 4 ... 7 Reserved
The Tx PDO contains the output data supplied by the encoder.
