I have been trying to get modbus TCP to work on a teknic clearcore to control a VSD on a CNC.
I uploaded the example modbus tcp sketch from the arduino Modbus library and if I set the board to any standard arduino board it compiles fine but if I set it to the teknic board it wont compile. with the below error
I am trying to use the ethernet port to run tcp/ip because I need the other com ports for other coms. I Have managed to open a connection with the drive over ethernet but I get problems when I try to introduce the ArduinoModbus library.
Can anyone point me in the right direction?
Heres the example code
/*
Ethernet Modbus TCP Client Toggle
This sketch toggles the coil of a Modbus TCP server connected
on and off every second.
Circuit:
- Any Arduino MKR Board
- MKR ETH Shield

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield

};
IPAddress ip(192, 168, 1, 177);
EthernetClient ethClient;
ModbusTCPClient modbusTCPClient(ethClient);
IPAddress server(192, 168, 1, 10); // update with the IP Address of your Modbus server
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield was not found. Sorry, can't run without hardware. :(");
while (true) {
delay(1); // do nothing, no point running without Ethernet hardware
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println("Ethernet cable is not connected.");
}
}
void loop() {
if (!modbusTCPClient.connected()) {
// client not connected, start the Modbus TCP client
Serial.println("Attempting to connect to Modbus TCP server");
if (!modbusTCPClient.begin(server, 502)) {
Serial.println("Modbus TCP Client failed to connect!");
} else {
Serial.println("Modbus TCP Client connected");
}
} else {
// client connected
// write the value of 0x01, to the coil at address 0x00
if (!modbusTCPClient.coilWrite(0x00, 0x01)) {
Serial.print("Failed to write coil! ");
Serial.println(modbusTCPClient.lastError());
}
// wait for 1 second
delay(1000);

if (!modbusTCPClient.coilWrite(0x00, 0x00)) {

Serial.println(modbusTCPClient.lastError());
}
// wait for 1 second
delay(1000);
}
}
and this is the error I get
