17 INM MTL83xC PC Modbus Rev 1
DRAFT - 06 January 2019
5 .4 Action Buttons
At the bottom of the channel area, there are four (4) buttons. Only
one of them is active (blue) because there is no MTL838C currently
communicating. This is the Reset Configs button. If pressed, it will
reset all 16 channels in the current tab to their defaults – which are as
shown in Figure 3 above (Input Type = mV, Safety Drive = None, Gain =
1, the remaining fields = 0).
The following figure (4) shows what the tab would look like when
communicating with an MTL838C that has one MTL831C connected
to it that has been configured with all channels as “TC, K, Temp, CJC”.
Notice that no channels are connected (the Open status and high
invalid reading). The Calibration status of the MTL831C is shown below
it and should always be “Good” as they are factory calibrated. Channel
1 is the only selected channel as it is highlighted (blue).
Now that there is a connected system the Download and Upload
buttons are active (blue). Pressing the Download button would
configure all of the channels on the MTL831C as mV – and pressing the
Upload button would bring the configuration in the MTL838C (for the
MTL831C #1) into the PC software. See the results of pressing these
buttons in figures 5 and 6 respectively.
The Sign Off button is not active. This means that the configuration
is considered valid. A configuration becomes invalid when the Data
Format on the MTL838C tab is changed and downloaded to the unit.
The sign-off must then be initiated by this button in the PC software
or by the Modbus Host via a Coil Write. See the COIL STATUS FLAGS
section of the INM838C-MBF document for more information.
