•
The information type of double commands for routing as Source system interface depends on the
information type of the associated checkback indication.
Only double commands with a double-point indication as checkback indication can be routed to the
positions in the Modbus TCP message which are reserved for double commands according to the
bus mapping.
Double commands with a single-point indication as checkback indication or without checkback indica-
tion are treated via Modbus TCP like single commands and must be routed to the positions reserved
for single commands.
•
Commands without checkback indication cannot be routed to the Destination system interface.
Reading the state of these command types is not possible via Modbus TCP.
Changing an Existing Allocation
If a routed information shall get another (empty) position in the Modbus TCP message, then this must be
done in the dialog Object properties.
Select the column Type in the row of the associated information in the DIGSI 4 Configuration Matrix and
