Q2524 COM2 mode 8838, g12 0
COM2 mode description
0 auto : use mwbus – automatic fall back to modbus slave
1 modbus : use standard modbus
If this port is connected to an external modbus master, then this should be set to modbus.
Q2520 COM2 error count 8812, g12 Hz
Shows the operating mode (MWBUS or MODBUS). The ‘cycle time’ is the MR1 update rate. A list of
device addresses on the bus is shown.
Communications error counts are shown, which should usually
read 0.

Q2531 COM3 baud rate (8 data, no parity, 2 stop) 8588, g12 115200
Sets the communications speed.

Interface registers
These registers are the recommended registers to use for extracting the basic signals from the trans-
mitter via Modbus. The advantage of using these registers is that multi-register Modbus commands can
be used to make the interface more efficient.
A control or status register contains 32 bits of on or off information. When one of these registers is
displayed, a bit is selected by using the left and right arrow keys.
