Sm Devices - Mitsubishi Electric GOT2000 Series Connection Manual

2.4.6

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).
Address
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.
The data amount (number of bytes) to be interrupt-output is set at "Interrupt Data Byte" in "Communication Detail
Settings".

Address
SM0 to 49
1-second cycle clock
Turns ON/OFF at a 1-second cycle.
SM50
2-second cycle clock
Turns ON/OFF at a 2-second cycle.
SM51
Interrupt code output disable flag
Enables or disables the output of the interrupt code.
SM52 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.

After the ON/OFF state is changed, the interrupt data is output within a period of 1 to 10 ms.
When the ON/OFF state of SM0 to 49 is changed from the host side, interrupt output is not performed.
POINT POINT POINT
(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).
➠
2.4.6 SM devices
• To enable the interrupt output, set 8 bits to the data length at "Communication Detail
Settings".
➠
2.6.1 Setting communication interface (Controller Setting)
• When "7 bits" is set, the MSB (8th bit) is ignored. (Example: FFH
