Parameterization via Register Communication

The operating mode and the parameters for the 750-451 I/O module can be set
directly using the register communication.
The values for channel 1 are set via control and status bytes CH1_C0/CH1_S0 for
the addressing and via data bytes CH1_D0 and CH1_D1 for the transmission of
the values to be set.
Enter password!
Before writing to the user register 32 and following, "0x1235" must be written to
the password register 31.
The number of user registers depends on the I/O module used.
Bits 0 ... 5 of the control byte receive the register number.
Via bit 6 (R/W) of the control byte, the access direction (read/write) is set.
To switch ON register communication, bit 7 (Reg_Com) is set to "1" in the
control byte.
No access to process data during register communication!
During register communication, process data cannot be accessed! Resulting
process data that may be displayed will be invalid!
The values to be set are written to output data bytes CH1_D0 und CH1_D1.
Via the input data bytes CH_1D0 and CH1_D1, the set values can be read from
the I/O module.
Checking of the values set!
After writing the register, the set values can be checked by reading out the
register.
The corresponding bits of the control byte are mirrored in bits 0 ... 5 and 7 of the
status byte.
