Sm Devices - Mitsubishi Electric GT14 User Manual

61.4.6 SM devices

The SM devices are bit devices into which interrupt outputs and clock data that turn ON/OFF at 1-second cycles.

(1) The side where virtual devices are set
System: Set on the system side.
User: Set on the user side (by sending request messages from host or using the touch switches, etc. on the GOT).
(2) Interrupt outputs (SM0 to 49)
• To disable the interrupt output, turn ON SM52 (interrupt code output disable flag). (
• To issue interrupts, set the data length to "8 bits" at "Communication Detail Settings".
(
• When "7 bits" is set, the MSB (8th bit) is ignored. (Example: FF

61.4 Device Data Area
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.
The data amount (number of bytes) to be interrupt-output is set at "Interrupt Data Byte" in "Communication
Detail Settings". ( 61.6.1 Setting communication interface (Communication settings))

Enables or disables the output of the interrupt code.
OFF: Interrupt code output enabledON: Interrupt code output disabled
When set to disable the interrupt code output, no interrupt data are output to the host.
(Relevant devices: D13, D14, SM0 to 49)
After the ON/OFF state is changed, the interrupt data are output within a period of 1 to 10ms.
When the ON/OFF state of SM0 to 49 is changed from the host side, interrupt output is not performed.
