MP_EPIV_V4_Process
This function block is suitable for 2-way EPIV V4 DN 15..50 EP..R2+(K)BAC. 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. |
rSetpoint | LREAL | Setpoint in % (0...100) |
nCommand | E_MP_EV_V4_Command | Command for service and test functions of the actuator. |
nOverrideControl | E_MP_EV_V4_OverrideControl | Override the setpoint with defined values. |
nDataRead | WORD | 0xFFFF - read all data; bit 0 - read relative position; bit 1 - read absolute position; bit 2 - read value sensor 1; bit 3 - read analog setpoint; bit 4 - read relative volume flow rate; bit 5 - read absolute volume flow rate; bit 6 - read glycol concentration; bit 7 - read temperature1 remote; bit 8 - read temperature2 integrated; bit 9 - read temperature delta; bit 10 - read relative power; bit 11 - read absolute cooling power; bit 12 - read absolute heating power; bit 13 - total volume; bit 14 - cooling energy; bit 15 - heating energy |

Name | Type | Description |
---|---|---|
bBusy | BOOL | This bit is set for as long as the function block is active. |
bError | BOOL | This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable. |
iErrorId | This output outputs an error code in the event of an error. bError goes TRUE at the same time. | |
strMP_Serial_Number | MP_Serial_Number | Structure for the serial number |
