WIRE INSTALLATION
- Insert screwdriver and push wire locking mechanism open
- Insert wire
- Remove screwdriver
- Due to possible significant interference in industrial installations, appropriate measures assuring the correct operation of the unit must be applied.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
- For this reason, an external time-delay cut-out fuse with a small nominal current value must be used (recommended bipolar, max. 2A) and a power supply circuit breaker located near the unit.
- In the case of using a monopolar fuse, it must be mounted on the phase cable.

THE MODBUS PRO TOCOL HANDLING
- Transmission parameters: 1 start bit, 8 data bits, 1 or 2 stop bits (2 bits are sent, 1 and 2 bits are accepted when received), no parity control
- Baud rate: selectable from 1200 to 115200 bits/second
- Transmission protocol: MODBUS RTU compatible
- The device parameters and display value are available via the RS-485 interface, as HOLDING-type registers (numeric values are given in U2 code) of Modbus RTU protocol. The registers (or groups of the registers) can be read by the 03h function and written by 06h (single registers) or 10h (group of the registers) according to Modbus RTU specification. Maximum group size for 03h and 10h functions can not exceed 16 registers (for single frame).
- The device interprets the broadcast messages but then does not send the answers.

- these registers are active only if the device is equipped with current or voltage output
- after writing to register no 20h the device responds with an “old” address in the message.
- after writing to register no 22h the device responds with the new baud rate.
- the value of the “mbAc” parameter is also connected to write to this register, so it is possible to block writes, but impossible to unblock writes via the RS-485 interface, The unblocking of the writes is possible from the menu level only.
- the pairs of „X -Y” coordinates may be defined for any free point. The pair is “free” (it means that a particular point is not defined) if the „X” coordinate of this point is equal to 8000h. After writing both X and Y coordinates the point is defined and used in the calculation of the result. The coordinates of any point can be changed at any time.
TRANSMISSION ERRORS DESCRIPTION
- If an error occurs while writing or reading of single register, then the device sends an error code according to Modbus RTU specifications (example message no 1).
Error codes:
- 01h – illegal function (only functions 03h, 06h and 10h are available),
- 02h – illegal register address
- 03h – illegal data value
- 08h – no write permission ( see: “mbAc” parameter)
- A0h – exceed of upper border of input range
- 60h – exceed of lower border of input range
- A0h and 60h codes can appear only during reg. 01h is reading by 03h function (read of a single register).
