Modem (FB)¶

FUNCTION_BLOCK Modem EXTENDS CBM.ETrigTo

This function block represents the physical device; therefor only one instance should exist for one physical modem.

It has to be initialized once, to get a connection to the modem, set the pin if required and check the network status.

InOut:

Scope	Name	Type	Comment	Inherited from
Input	`xExecute`	`BOOL`	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (`xDone`, `xError`) are present at the outputs for exactly one cycle.	ETrigTo
Input	`udiTimeOut`	`UDINT`	Defines the time (µs) after which an FB (e.g. requiring an external acknowledgement) aborts operation due to a timeout with error message.	ETrigTo
Output	`xDone`	`BOOL`	`TRUE`: Action successfully completed	ETrigTo
	`xBusy`	`BOOL`	`TRUE`: Function block active	ETrigTo
	`xError`	`BOOL`	`TRUE`: Error occurred, function block aborts action `FALSE`: No error	ETrigTo
Input	`itfConnectionType`	ITFConnection	The function which implements this interface. The connection parameters must be added to this function block.
Input	`sPin`	`STRING(10)`	The pin for the sim card which is included in the GSM modem
Output	`eError`	ERROR	error code
