Operation

6. Operation
In the operation mode the module is controlled by a network Master in Modbus network.
In addition, the input states and counter states can be read out and the counter states
can be set to 0 (see 6.1).
Modbus functions 03, 04 for reading and 16 for writing can be used.
6.1

Input and counter status

The input status can be read out as a bitmask. The corresponding Modbus registers can
be taken from the table 6.1. The least significant bit of the mask corresponds to the
input 1.
To reset the counter, write 0 to the corresponding register.
6.2

Fault condition

If the data exchange on the serial port is interrupted (i. e. there is no command from the
master within the time specified by the parameter t.out), the following applies:
–
LED FAULT flashes.
–
Once a request from the master device comes, the display 'refreshes'.
–
If t.out parameter is set to 0, 'Fault Condition' is not defined.
6.3

Memory addressing

All variables and parameters in the Table 6.2 are of the type UNIT16.
R – read access
W – write access
