Type of variable : A =analogue, D=digital, I=integer
SVP= variable address with CAREL protocol on 485 serial card.
ModBus® : variable address with ModBus® protocol on 485 serial card.
The selection between CAREL and ModBus® protocol is automatic. For both of them the speed is xed to 19200 bit/s.
All the devices connected to the same network must feature the same serial parameters: - 8 data bit;
- 1 start bit;
- 2 stop bit;
- no parity check;
- 19200 baud rate.
