6.5 Module type and error code registers for I/O exten-
sion modules
Registers 30xx0 and 40xx0 can be used to read the module type and data timeliness of the
I/O extension modules.
The individual I/O extension modules can be clearly distinguished by the module type. The
module type ID of the extension module can be read in the Modbus register.
Table 6-5 Module type IDs
“Module type” register value
If the module type in the register is invalid or not available, then the register value is 0.
“Timeliness of data” register value
If the data in the register is not up to date, then the register value is 1. This is the case, for
example, if the wireless connection to an input module fails. The IN process data is then re-
tained in the Modbus table, but is no longer updated. In the case of an output module, the
“timeliness of data” register value is set to 1 until the OUT process data has been written to
the Modbus registers. The read I/O data is only valid and up to date if a valid module type
value is returned by the slave and the “timeliness of data” register value is 0.
