Description
MDIS device protocol is used to control input-output peripherals and hardware of watchdog of devices produced by the MEN company.
Communication line configuration
- Communication line category: API
Communication station configuration
Station protocol parameters
| Parameter | Description | Default value |
|---|---|---|
Full Debug | Logging is enhanced with listings that enable fast error detection. | NO |
I/O Interface Name | Unique text identifier of interface with binary input-outputs. | z17_9 |
Watchdog Interface Name | Unique text identifier of the interface of HW watchdog. | xm01bc_1 |
Control Interface Name | Unique text identifier of the interface that is used to configure other interfaces. | z17_1 |
Configuration of interfaces
The configuration of MDIS5 interfaces is possible through Device Manager of Windows OD, on the "MDIS5 devices" tab.
Types of interfaces can be identified by their name. Binary IO peripheral is a device called 16Z037_GPIO. The name of the configuration interface is 16Z034_GPIO. In Device Manager, you may find more devices of the same name. Therefore, you should display the properties to identify the particular interface. This interface should be placed in "cham-slot 2(is instance 2)" (see figure below). Next interface is HW watchdog, its name is XM01BC.
Each of these devices can be addressed via its unique identifier. The modification of identifier can be done in "Device Manager -> MDIS device -> Properties -> "Device Settings" tab.
I/O tag configuration
Possible I/O tag types: Ai, Ao, Ci, Co, Di, Do.
Addresses of digital inputs 1-8: DIx, e.g. DI1, DI2 .. DI8
Addresses of digital outputs 1-8: DOx, e.g. DO1, DO2 .. DO8
Addresses related to watchdogs:
| Address | Description |
|---|---|
| WD_TIME | Set / query the watchdog time (in milliseconds) |
| WD_ACTIVE | Set / query the watchdog status (0-inactive, 1-active) |
| WD_SHUTDOWNSTATE | Set / query the shutdown status (0 - watchdog shot, 1-watchdog didn't shoot) |
| WD_TRIGGER | Activation (triggering ) of the watchdog |
