Hello people,
I am trying to find out how to map 8-bit data types onto Modbus registers.
Since registers are always 16 bits, does it even make sense to provide data types of 8 bits length? In case of 8 bits, I saw many devices where one of the two bytes of a register is set to zero.
Does it make sense from the PLCs point of view? Does this save memory?
Are 8-bit data types obsolete for Modbus? Are PLCs able to handle two 8-bit values within a single register?
I would like to learn about your opinions and experiences.
Thanks in advance.
Jay
