How to use Ace PLCs with 2 serial ports as a serial Gateway<\/h1>\n
The Ace with 2 serial ports<\/strong> can be used as a serial gateway. If you want for example to convert a serial message from an equipment which include data to another serial equipment with the same data. This can be used with different speeds and parities parameters.<\/div>\n
<\/div>\n
For this operation you must have an Ace PLC with 2 RS232 or RS485 port.<\/div>\n
<\/div>\n
You must link each serial port to your devices.

GatewaySerialSub<\/a>\u00a0program to your Ace with vBuilder (Unzip the file before)
\nThis program is for Ace 7096x version. Check the version in the “Setup Hardware”. Change it if needed.
\nYou must also configure the serial port as Custom type<\/strong> and all other parameters depending of your equipments configurations.<\/p>\n\n\n\n

How\u00a0does <\/span><\/span> the program work ?<\/h3>\n

The program is a subroutine called “SerialA1toA2”.<\/p>\n

In the main program, we call this subroutine at each program cycle.
\nNbMess.Processed<\/strong> (in the main program) and NbMessagReceived <\/strong>(in the subroutine) is the number of messages processed. This is just for information.<\/p>\n

In our case here, the length of the received message is 14. The length of the message sent is 42. You must adjust these values for your application according to the length of your messages.<\/span><\/span>
\nThe tags ReceivedArray<\/strong> and SendArray<\/strong> are arrays of size respectivley 14 and 42.
\nThe values in the array tags must be in decimal. See https:\/\/en.wikipedia.org\/wiki\/ASCII<\/a>
\nIn the subroutine, you have different state :
\nState 0: We open and listen to the serial port A1.
\nState 1: We check if any message arrives. If nothing arrives after “MyTimer<\/strong>“, we reopen the serial port (State 0).
\nState 2: The message from A1 port is already in ReceivedArray<\/strong>. We create the new message and send it to the A2 serial port.
\nIn this example bellow, the new message sent (SendArray<\/strong>) contains fixe values and values from the ReceivedArray<\/strong>.
\n\"\"
\nState 3: Once the message is sent to the A2 serial port, we increment the number of messages received and we return to listen (State 0)<\/p>\n

Result:
\nIn this image bellow, we can see the value “+1234567” form\u00a0ReceivedArray<\/strong> copied to SendArray<\/strong><\/p>\n
