4. MR-MT2010 SSCNET III/H HEAD MODULE
4.1 Summary
The MR-MT2010 SSCNET III/H head module is used for SSCNET III/H communications.
This module is necessary to use a sensing module. Connect extension modules to this module. This module
can be used alone because it has digital I/Os.

Note 1. This is the maximum value of when four extension modules are connected to a head module. The current capacity can be
decreased by reducing the number of connected extension modules.
2. The number of the points will be four points when extension modules are connected.
3. This value is applicable when the output current is 50 mA or more.

This function sends the status of digital input signals to the controller.
This function turns on/off digital output signals using commands issued from the controller.
This function sends the timing to input digital input signals to the controller.
This function digitally outputs values depending on the level of each monitor value of the pulse
I/O module, analog I/O module, and encoder I/F module. Values can be digitally output
without the controller.
This function sets whether to hold or clear the preceding outputs when communications with
the controller are interrupted.
