MP_TEM_Process
This function block is suitable for the Thermal Energy Meter type 22PE-.. and 22PEM-.. . For more information please visit www.belimo.com.
MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bStart activates communication with the MP-Bus device. bBusy indicates that the function block is active. If bStart remains TRUE, the device is addressed cyclically with a period specified by the time in TMPolling. The time should be set longer than 1 second. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.

Name | Type | Description |
---|---|---|
MP_Address | USINT | MP-Bus address of the slave. |
bStart | BOOL | A positive edge starts the function block. If this remains continuously TRUE, the function block will be activated cyclically with a period specified by the time in TMPolling. |
strDataKL6771 | The data structure with which the KL6771() function block must be linked. | |
TMpolling | TIME | The time for which the function block should address the actuator. Default 10 s, minimum time 1 s. |
