information directly for the access to coils or Descrete Inputs. Converting the address syntax is
necessary for a register- wise access (refer to the table “Implemented modbus functions”).
In case there are no outputs or inputs, the register entry is 0xFFFF.
4.4.32 0x8000 – 0x87FF Process Data Inputs
For each module a data length of 64 bytes (32 registers) is reserved.
Example: Module 3 starts at address 0x8040.
4.4.33 0x9000 – 0x97FF Process Data Outputs
For each module a data length of 64 bytes (32 registers) is reserved.
Example: Module 3 starts at address 0x9040.
4.4.34 0xA000 – 0xA7FF Diagnostics
For each module a diagnostics data length of 64 bytes (32 registers) is reserved.
Example: Module 3 starts at address 0xA040.
In case of a diagnostics message, the 47 bytes of the module diagnosis are entered here from the
corresponding tables (see the table of diagnostic data in the corresponding module description in the
module chapter).
If a 1 is set in register 0x1134, reading out the corresponding diagnosis results in a confirmation of
the alarm.
4.4.35 0xB000 – 0xB7FF Process Alarms
For each module a process alarm data length of 64 bytes (32 registers) is reserved.
Example: Module 3 starts at address 0xB040.
In case of a process alarm, the 4 bytes of the module are entered here from the corresponding table
(see the table of process alarms in the corresponding module description in the module chapter).
4.4.36 0xC000 – 0xFFFF Parameters
For each module a parameter data length of 256 registers is reserved. Example: Module 3 starts with
address 0xC040. The modules can be parametrizes via the web server (s. Chapter 10) or via the
Modbus master.
One register is assigned to each module parameter with a size of max. 16 bit. 32 bit parameters use
two subsequent registers (consider Motorola format!). The sequence of parameters as well as the
optional values are listed in the parameter tables of the individual module descriptions (s. Chapter 6).
Example: Parameter 8 of module 3 has the address 0xC207 (provided that there is no 32 bit
parameter prior to it in the same module).
Examples for 32 bit parameters are “Period duration“ of
the pulse width modulation modules and „End value“ of the counter modules.
