Appendix A Modbus Address Setting - HACH LANGE RTC103 N-Module User Manual

Appendix A MODBUS address setting

The same slave address must be set for Modbus communication both on the sc1000
controller display and on the RTC103 N-Module. Since 20 slave numbers are reserved for
internal purposes, the following numbers are available for assignment:
1, 21, 41, 61, 81, 101...
The start address 41 is preset at the factory.
If this address is to be or must be changed because, for example, it has already been allocated
for another RTC module the changes must be made both on the sc1000 controller and on the CF
card of the RTC module.
This can only be done by the manufacturer service department
