Appendix A Module Tags
Output Tags
This screen capture shows the tags that are described in the following table.
Table 27 describes the output tags of channel 1 configured to the Generic ASCII
Table 27 - Generic ASCII Output Module Tags
Name Data Type Definition Valid Values
O x .ASCII.TxID SINT This ID is incremented when you want to transmit data from the
serial port. • -128…+127
(1)
O x .ASCII.RxID SINT This ID is incremented when you receive data from the serial
port. It is only used in Master/Slave Handshake Mode. • -128…+127
(1)
O x .ASCII.TxDataLength INT Length of Transmitted Data of each channel. • 1…256
O x .ASCII.RxDataLength INT Length of Received Data of each channel. • 1…256
O x .ASCII.ClearBuffer BOOL If Clear Buffer the bit changes from 0 to 1, the Receive and
Transaction buffer is cleared.
In Half Duplex, the RTS signal level is cleared (set to Inactive)
When it is at 0: Clearbuffer is triggered. • 0 = No Change
• 1 = Buffer Cleared
O x .ASCII.DTR BOOL Signal level of DTR line sent out when rising edge of EXEC bit is
detected. • 0 = Inactive
• 1 = Active
O x .ASCII.RTS BOOL Signal level of the RTS line sent out when rising edge of EXEC bit
is detected. • 0 = Inactive
• 1 = Active
O x .ASCII.EXEC BOOL If EXEC bit changes 0 to 1, FW will output a signal level that is set
in the DTR/RTS tag. • 0 = Inactive
• 1 = Active
Ox.ASCII.TxData[x] SINT (256) Output data from module. • -128…+127
(1) The value of 0 must be skipped except during module power-up.
