Creating Channels

1. Navigate to Devices → Channels
2. Click New Channel or Plus button
3. Select protocol from list
4. Configure:
   • Channel Name - Unique identifier
   • Description - Documentation
5. Click OK

Channel Properties

Core Settings

Interface Types

Serial

• RS-232/485 communication
• Single port configuration
• Hardware handshaking options

Multi Serial

• Multiple RS-232 ports
• Port count configuration
• Independent port settings

TCP/IP

• Ethernet/wireless networks
• Connection pooling
• Multiple simultaneous connections

Interface Settings

TCP/IP Settings

Serial Settings

• Baud Rate - Communication speed
• Data Bits - 7 or 8
• Parity - None, Even, Odd
• Stop Bits - 1 or 2
• Handshake - None, RTS/CTS, XON/XOFF

Channel States

emote Channels

Configure channels to run Execute Device Module on remote computers :for gateway and tunneling applications.

System Requirements

• All computers on same network
• Product installed on all computers
• Firewall ports configured

Configuration

1. Set InitialState to Remote
2. Configure RemoteSettings:

 RemoteSettings:
  Primary IP: 192.168.1.100:3100
   Backup IP: 192.168.1.101
  Port: 3101

Benefits:

:3100

Required Ports

Enable in firewall (Inbound/Outbound):

• WebServices: 10108, 80, 3100
• TServer: 3101
• Custom ports as configured

Remote Execution Process

1. TStartup connects to remote TWebServer/IIS
2. TRemoteDevice process launches on both computers
3. Remote computer executes channel operations
4. Data transmitted back to main server

Special Considerations

Runtime Control

Start/Stop Operations

csharp

// Stop channel
@Device.Channel.ChannelName.Stop();

// Start channel
@Device.Channel.ChannelName.Start();

// Stop with timeout
@Device.Channel.ChannelName.Stop(10);

Script Example

csharp

public class ChannelControl 
{
    public void RestartChannel(string channelName)
    {
        // Stop channel
        @Device.Channel[channelName].Stop(5);
        
        // Wait for stop
        Thread.Sleep(1000);
        
        // Start channel
        @Device.Channel[channelName].Start();
    }
}

Common Configurations

Modbus TCP

Protocol: Modbus
Interface: TCP/IP
Port: 502
Node Connection: 1
Timeout: 1000ms

Serial RS-485

Protocol: Modbus RTU
Interface: Serial
Baud: 19200
Data Bits: 8
Parity: Even
Stop Bits: 1

OPC UA

Protocol: OPC UA
Interface: TCP/IP
Port: 4840
Security: Basic256
Max Connections: 5

Best Practices Checklist

•  Name Channels Clearly - Include protocol and purpose
•  Document Settings - Use description field
•  Set Appropriate Timeouts - Match network conditions
•  Configure Connection Limits - Prevent overload
•  Use Remote Channels - For distributed systems
•  Monitor Channel Status - Track communication health
•  Test Before Production - Verify all settings

Troubleshooting

Channel won't start:

• Check InitialState setting
• Verify protocol license
• Review interface configuration
• Check port availability

Communication timeouts:

• Increase timeout value
• Check network latency
• Verify device response time
• Review connection settings

Connection failures:

• Verify IP addresses
• Check firewall rules
• Test network connectivity
• Review security settings

Remote channel issues:

• Verify remote computer online
• Check remote settings
• Test network path
• Review firewall exceptions

Diagnostics

Remote Channel Monitoring

Verification Steps

1. Check TStartup shows "Module Device started remotely"
2. Verify TRemoteDevice process on server
3. Confirm TRemoteDevice on remote computer
4. Monitor command line parameters

Monitor channel performance:

csharp

// Get channel status
bool isConnected = @Device.Channel.ChannelName.IsConnected;

// Check last error
string error = @Device.Channel.ChannelName.LastError;

// Get statistics
int successCount = @Device.Channel.ChannelName.SuccessCount;
int errorCount = @Device.Channel.ChannelName.ErrorCount;
