6. Modbus Wiring 2-Wire RS-485 4-Wire RS-485
+ connects to + and – connects to -
4-Wire RS-485
+’s and –’s are swapped
TX+ > RX+, TX- > RX-, etc.

7. Modbus Configuration
Modbus Address, Parity, Baud Rate

8. Incorrect Sepam Port selection
Sepam 80 has dual comm and remote module ports

9. ION Master Connections
To communicate to an ION meter there are two communication port settings that need to be made.
Comm port on the meter needs to be set to Modbus Master
Modbus Master Options Module must have the comm port assigned to ModbusGate Connection

13. Common Wrench Errors Wrench 1 (most common) Wrench 2 Wrench 3 Wrench 4
Typically CCA63x (CT module) is absent
I/O module is absent
Wrench 2
Typically caused by faulty wiring between remote module connection.
Wrench 3
MET148-2 (Temp Module) module is not available
Wrench 4
MSA141 (Analog Module) is not available
DSM303 (Remote Display) is not available
Wrench 5
MCS025 (Sync-Check) is not available
Wrench 10
CPU overload (Sepam 80 only) typically caused by excessively large Logipam program

14. Wrench 1 (Most Common)

15. Wrench 1 Normally caused by: CT module not attached to relay
I/O card is configured in the software but is not attached to relay
If you are unable to connect with SFT2841 it could indicate a major fault with the base unit
On Sepam 80 it could indicate a faulty memory cartridge
