com.intelligt.modbus.jlibmodbus.exception.ModbusIOException: java.net.SocketTimeoutException: Read timed out #99
Description
Cycling through register addresses results in a "read timed out" error, but reading the same address repeatedly in a loop works fine. The test code is as follows:
@test
public void testJLibModbus() throws Exception {
String ip = "192.168.1.31";
int port = 8899;
TcpParameters tcpParameters = new TcpParameters();
tcpParameters.setHost(InetAddress.getByName(ip));
tcpParameters.setPort(port);
tcpParameters.setKeepAlive(true);
ModbusMaster master = ModbusMasterFactory.createModbusMasterTCP(tcpParameters);
Modbus.setAutoIncrementTransactionId(true);
master.setResponseTimeout(1000);
log.info("master isConnected: {}", master.isConnected());
int startAddress = 0x1000;
Thread.sleep(50);
for (int i = 0; i < 100; i++) {
int[] registers1111 = master.readHoldingRegisters(1, startAddress, 122);
log.info("registers1111：{}", registers1111);
int[] registers2222 = master.readHoldingRegisters(1, CommandEnum.BAT_WATT.getCode(), 6);
log.info("registers2222：{}", registers2222);
int[] registers333 = master.readHoldingRegisters(1, CommandEnum.BALANCE_CURRENT.getCode(), 14);
log.info("registers333：{}", registers333);
}
}
exception：
