[sinofteceng]

HELLO,
I am trying to control the BLV R with siemens 1200 (CB 1241 RS485 with BLV R ID1 and Cm1241 with drive ID2)
PORT" :="Local~CB_1241_(RS485)";
BAUD := 115200;
PARITY := 0;
FLOW_CTRL := 0;
RTS_ON_DLY:= 0;
RESP_TO := 1000;
MODE := 4;///two wire rs485
mbAddr := 1;
Same thing for the second slave except for the port and the ID=2
On the drive side:
See the attached pictures:
communication mode = 2:Modbus RTU(RS-485 Communication)
communication power supply action 2: Follow QSTOP setting (current is not cut off )

CANOPEN ID ID=2
CANOPEN BITRATE 500 kbps

RS485 TERMINATION RESISTOR -1:Enable
FRAME MONITOR TARGET ID ID=2

SLAVE ADDRESS ID=2
BAUD RATE 115200 bps
BIT AND WORD ORDER 0:EvenAddress-HighWord & Big-Endian

assigned registers with their Net ID to be read:
80
97
