2.1.1.9.3 Parameterization via Register Communication
The operating mode and the parameters for the 750-563 module can be set
using the register communication.
The values for channel 1 are set via control and status bytes C0/S0 for the
addressing and via data bytes D0 and D1 for the transmission of the values to
be set.
Attention
Before writing the registers 32 to 39, the password register 31 must be
written with "0x1235."
The bits 0 ... 5 of the control byte contain the register number.
Via bit 6 (R/W) of the control byte, the access direction (read/write) is set.
To switch on the register communication, bit 7 (Reg_Com) is set to "1" in the
control byte.
Attention
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 into the output data bytes D0 and D1.
Via the input data bytes D0 and D1, the set values can be read out of the
module.
Note
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.
Attention
After writing to the registers, password register 31 must be reset with
"0x0000". Otherwise write access to these registers is possible until the
supply voltage is disconnected.
Analogous to channel 1, the setting for channel 2 occurs via the control and
status bytes C1/S1 as well as the data bytes D2 and D3.
