Register 1130h: Modbus connection mode
This register defines the behavior of the Modbus connections:
Register 1131h: Modbus Connection Timeout
This register defines after which time of inactivity a Modbus-connection is closed through a Discon-
nect.
Behavior of the BUS LED
In case of a Connection Timeout the BUS LED's behavior is as follows:
Register 0x113C and 0x113D: Restore Modbus-Connection-Parameters
Registers 0x113C and 0x113D serve for resetting the parameter-register 0x1120 and 0x1130 to
0x113B to the default settings.
Follow the following steps in order to reset the parameter register:

Write 0x6C6F to register 0×113C.

To activate the reset of the registers, write 0x6164 ("load") within 30 seconds in register 0x113D.
Both registers can also be written with one single request using the function codes FC16 and FC23.
The service resets the parameters without saving them. This can be achieved by using a following
"save" service.
Bit Name
Description
0 MB_OnlyOneWritePermission
–
0: all Modbus-connections receive the write authorization
–
1: Only one Modbus-connection can receive the write permission. A write permission is opened until
a Disconnect. After the Disconnect the next connection which requests a write access receives the
write authorization.
1 MB_ImmediateWritePermission
–
0: With the first write access, a write authorization for the respective Modbus-connection is
requested. If this request fails, an exception response with exception-code 0x01 is generated. If the
request is accepted, the write access is executed and the write authorization remains active until
the connection is closed.
–
1: The write authorization for the respective Modbus-connection is already opened during the con-
nection establishment. The first Modbus-connection thus receives the write authorization, all fol-
lowing connections don’t (only if bit 0 = 1).
