19.4.6 SM devices
The SM devices are bit devices into which interrupt outputs and clock data that turn ON/OFF at 1-second
cycles.
1 List of SM devices
The following shows the SM devices (virtual devices inside the GOT).
*1 After the ON/OFF state is changed, the interrupt data are output within a period of 1 to 10 ms.
*2 When the ON/OFF state of SM0 to 49 is changed from the host side, interrupt output is not performed.
Address Description Set side
SM0 to 49
Interrupt output
When the ON/OFF state of SM0 to 49 is changed by a touch switch on the GOT, for example, the
interrupt codes shown below are transmitted (interrupt output) to the host side.
*1*2
The data amount (number of bytes) to be interrupt-output is set at "Interrupt Data Byte" in
"Communication Detail Settings". ( Section 19.6.3 Setting communication interface
(Communication settings))
User
SM50
1-second cycle clock

System
SM51
2-second cycle clock
Turns ON/OFF at a 2-second cycle.
SM52
Interrupt code output disable flag
Enables or disables the output of the interrupt code.
OFF : Interrupt code output enabled
ON : Interrupt code output disabled
When set to disable the interrupt code output, no interrupt data are output to the host.
