Set signal address

This field shows the address on the remote MODBUS server. Use the on-screen keypad to

choose a different address. Valid addresses depends on the manufacturer and configuration of

the remote MODBUS unit.

Set signal name

Using the on-screen keyboard, the user can give the signal a name. This name is used when the

signal is used in programs.

Signal value

Here, the current value of the signal is shown. For register signals, the value is expressed as an

unsigned integer. For output signals, the desired signal value can be set using the button. Again,

for a register output, the value to write to the unit must be supplied as an unsigned integer.

Signal connectivity status

This icon shows whether the signal can be properly read/written (green), or if the unit responds

unexpected or is not reachable (gray). If a MODBUS exception response is received, the response

code is displayed. The MODBUS-TCP Exception responses are:

ILLEGAL FUNCTION (0x01) The function code received in the query is not an allowable action

for the server (or slave).

ILLEGAL DATA ADDRESS (0x02) The function code received in the query is not an allowable

action for the server (or slave), check that the entered signal address corresponds to the

setup of the remote MODBUS server.

ILLEGAL DATA VALUE (0x03) A value contained in the query data field is not an allowable

value for server (or slave), check that the enterd signal value is valid for the specified

address on the remote MODBUS server.

SLAVE DEVICE FAILURE (0x04) An unrecoverable error occurred while the server (or slave)

was attempting to perform the requested action.

ACKNOWLEDGE (0x05) Specialized use in conjunction with programming commands sent to

the remote MODBUS unit.

SLAVE DEVICE BUSY (0x06) Specialized use in conjunction with programming commands

sent to the remote MODBUS unit, the slave (server) is not able to respond now.
