No
Device profile
None
Add-on modules comply with
MODBUS over serial line specification & implementation guide v. 1.0
modbus.org 12/02/02
MODBUS application protocol specification v. 1.1
modbus.org 12/06/02
Isolation
500 V AC functional isolation of data signals and common
Add-on modules must be connected to equipment complying with "Low Voltage Directive" in
order to be considered safe. The isolation within the MAG 8000 and MAG 8000 CT add-on
MODBUS module is only functional isolation.
