1
- if overflow or underflow occurs (
-Hi-
or
-Lo-
), read of registers 01h, 02h and 03h (single registers) it returns
recalculated number of pulses ( while the overload of display quantity is very big this value can be erroneous).
Register 03h returns according error code.
2
- Preset of 0000h to these registers ( 04h÷ 0Dh ) causes by zeroing of main counter and precounter content
3
- after writing to register no 20h the device responds with an old address in the message.
4
- after writing to register no 22h the device responds with the new baud rate.
5
- the value of the
mbAc
parameter is also connected to write to this register, so it is possible to block a writes, but
impossible to unblock writes via RS-485 interface, The unblocking of the writes is possible from menu level only.
6
- n
umbers written to holding registers of relays thresholds are interrelated with each other auto-correction.
For example. Preset to reg. 31h (threshold lower word) of value, which together with content of register 30h
(threshold higher word) gets value from behind of allowable range, will fails. Over more preset to reg 30h of value
which together with content of register 31h gets value from behind of allowable range, will modify the content of
register 31h, in that way to it's value together with register 30h be located in allowable range. If appropriate
modification is impossible, write fails.
It is recommended to write threshold values in presented manner: first preset of
threshold higher word, and next threshold lower word. Similarly storing thresholds registers of another relays is
realised with each other correction.

TRANSMISSION ERRORS DESCRIPTION
If an error occurs while write or read of single register, then the device sends an error
code according to Modbus RTU specifications.
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:
mbAccE
parameter)
