The offset value is used to convert the virtual ID to the actual ID This specifies the range of IDs that will be routed to the numeric range from selected set of slave devices For example you can specify Virtual Slaves ID Range 1 to 254 that IDs between 8 and 24 be routed to the devices on Port 3 The ID 255 is reserved for the gateway itself This specifies the difference between the virtual slave ID number between and the actual slave ID If a slave s virtual ID is 16 and the 253 and 253 actual ID is 5 you would set the offset to 11 This offset is applied to the entire range of virtual slave IDs Slave ID Offset When a serial port is set to RTU slave or ASCII slave mode a virtual ID range will already be created for you Simple select the entry in the table and modify the range and offset as needed For TCP slaves you can add an entry that assigns a range of virtual IDs to a specific IP address using the Remote TCP Slave IP setting Slave ID Map Example Suppose you have two ASCII slave devices on port 1 assigned to slave IDs 3 and 5 The MGate will automatically create a virtual ID range for port 1 which you will need to modify If slave IDs 3 and 5 are already in use by TCP slaves the virtual ID range should be set to IDs that are not in use such as 20 through 22 In that case you would specify a slave ID offset of 17 since that is the difference between the virtual ID range and the actual slave IDs The formula
