Registers in Manufacturer Zone

Input Registers

The following table shows register mapping for expansion module input value. Note this is for backward compatibility purposes with legacy products and application:

Register	Function	Description
0	Not used	-
1	Input value of first expansion module with inputs	Varies depending on module
...	-	-
99	-	-

Output Registers

The following table shows register mapping for expansion module output value. Note this is for backward compatibility purposes with legacy products and application:

Register	Function	Description
100	Not used	-
101	Output value of first expansion module with outputs	Varies depending on module
...	-	-
199	-	-

Diagnostics Registers

Diagnostic registers manage alert and alarm conditions. There are diagnostics registers dedicated for configuration errors, IO module errors, and communication errors among others. Refer to status diagnostic table.

Management Registers

The following table shows the bus coupler module management registers:

Registers	Functions
1000 - 1004	Reserved registers
1005	Reset expansion bus. This function is used to update the new expansion module I/O parameters. NOTE: All outputs are set to zero when the bus is reset.
1006 - 1007	Reserved registers
1009	Fieldbus timeout counter
1010 - 1049	Reserved registers

Managing the Serial Line Connection

The following table shows the serial line connection management registers:

Registers	Function
1050	Slave serial line address
1051	Baud rate
1052	Baud rate
1053	Parity (Default Even - 2)
1054	Mode (RTU - 0)
1055 - 1099	Reserved registers

NOTE: This is for information only. Modifying the values has no impact on the configuration.
