Station addressing is supported by appending the slave address and a colon, before the actual address. If you want to access bit five in holding register 40037, the address should be: 40037.5 Slave addressing This is done by adding a point followed by the bit number (0-15) to address. With bit addressing it is possible to access individual bits within a 16-bit register. 400007 Bit addressing in 16-bit registers 40007 Analog signals – Extended addressingģ00000 – 365535 Input registers – Read only. 100007 Analog signals – Standard addressingģ0000 – 39999 Input registers – Read only. 7ġ0000 – 19999 Inputs, decimal addressing – Read only. Digital signals – Standard addressingĠ - 9999 Coils, decimal addressing. The following signal types are available and implemented in the driver. Leaving this unchecked means that the first register is the least significant register. You to set if the first register is the least significant register or the most significant register. Word Swapped – When combining two 16-bit registers into one 32-bit register, this setting allows Register and holding register is coil, input, input register and holding register one. With address base one, the first coil, input, input Input, input register and holding register zero. Big-endian have most significant byte first while little-endian have leastĪddress Base – With address base zero, the first coil, input, input register and holding register is coil, Slave address – If no slave address field, this slave address is used, this is rarely changed.Įndian – Little Endian (Motorola) or Big Endian(Intel), defines how high byte and low byte areĪrranged for 16-bit registers. The default port is 502, this is rarely changed. Port – The TCP port of the Modbus TCP Slave.

For further information about how to set up the device, cable specifications and information on how to use the device we refer to the manuals for those devices Driver settingsĪddress – This is the IP-address of the Modbus TCP Slave. In order to be able to communicate with the controller CPU or a communication module, additional settings might have to be set up, using the controller programming software or other configuration software. Connection with controllers and communication modules

To extend the network a hub or switch may be used. Connecting to the controllerĬonnection in a network is made according to Ethernet standards.
