Y_IM_MainRTUDriver

Parameters

*	Parameter	Data Type	Description	Default
VAR_IN_OUT
B	ModbusInput	Yt_ByteArray60	Array of 60 bytes with actual values of the CP040 module. To have a consistent data access, please define the type of the connected variable as "IN Port".
B	ModbusOutput	Yt_ByteArray60	Array of 60 bytes with set values for the CP040 module. To have a consistent data access, please define the type of the connected variable as "OUT Port".
VAR_INPUT
B	Enable	BOOL	The function will continue to execute every scan while Enable is held high and there are no errors.	FALSE
VAR_OUTPUT
B	Valid	BOOL	Actual state of data exchange with CP040 module, TRUE=Enabled, FALSE=Disabled.
B	Busy	BOOL	Establishing communication with CP040 module is in progress
E	Error	BOOL	The Error output is set to TRUE if an error has occurred during the operation of the function block. The output is cleared when the Execute or Enable input becomes FALSE
E	ErrorID	UINT	The ErrorID output provides the identifier of the error when there is an active error in the function block execution. The output is cleared when the Execute or Enable input becomes FALSE

Y_IM_MainRTUDriver can handle up to 10 axes and 10 generic devices simultaneously
The Enable signal causes subsequent axes / devices to be queried for communication requests.
Axes / generic devices communication is done in sequence. There are no priorities. This means that for the same axis / device, a telegram can only be sent when all devices before have been checked for communication requests
If a communication error is detected, the block will resume communication on its own and transmit the error number to the corresponding axis Y_MotionAxisDriver
The rising edge of the enable signal causes a one-time reset of CP040 module
Failure to communicate with CP040 module will result in a block initialization error
