INM MTL83xC PC Modbus Rev 4
6.3 Devices
The Devices menu contains functions specific to the MTL83xC devices. The first
three are commands to reset the respective pieces of hardware and the fourth item
launches the window allowing firmware updates of the connected devices.
All three Reset functions send a command to the selected device that tells it to reset
itself (firmware reset). This will only work if the devices are functioning well enough
to receive and execute the command.
A Reset MTL838C command not only causes the MTL838C to reset (assuming it is
successful), but it also may reset the connected MTL831Cs. If the MTL831Cs are
powered by the MTL838C (non-hazardous installation), then reseting the MTL838C
will also reset the connected MTL831Cs. However, if the MTL831Cs are powered
by an isolator such as the MTL5553, then a reset to the MTL838C will not reset the
MTL831Cs.
The other two reset commands are for the MTL831C #1 and MTL831C #2
respectively. Again, assuming the MTL838C is functioning properly the command
will be routed to the appropriate MTL831C. Then if that MTL831C is also functioning
well enough, it will reset itself.
The reset commands may be used if you feel that a unit is not functioning correctly
and it may save a trip into the field.
Selecting the Update Firmware option brings up the following window:
