I/O Module Status
This bit turns on when the voltage is below 18V DC. This is the only indication that some
sensors or valve modules may not function properly. All bits will be on when an I/O bus fault
has occurred, which alerts the user that the I/O data is no longer valid.
Error Location
This bit turns on to indicate which module has caused the fault that is indicated in the error
code. There is one bit for each possible module. Example: bit0=module1
