The format of the RPDO1 and RPDO2 is:
8 Bit 8 Bit
LDM select Command byte
Note: On PC6D the LDM selector byte is ignored.
The command byte of RPDO1 is used as follows:
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
Cmd: SnG SnN RZ SZ RT ST
Where
- SnG means select Gross Weight
- SnN means select Net Weight
- ST means Set Tare
- RT means Reset (Clear) Tare
- SZ means Set Zero
- RZ means Reset (Clear) Zero
The command byte of RPDO2 is used as follows:
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
Cmd: TR TS
Where
- TR is a software trigger that starts an average measurement.
- TS Trigger Stop; stop triggered measurement(s).
3.2 Network management
The PC6D implements the Network Management protocol with the node guarding protocol.
The PC6D also implements an address setup feature. The network controller may change a
PC6D node address using COB-ID = 0.
The frame must be sent while the PC6D is in its PRE-OPERATIONAL state and it must have
the following contents:
8 bits 8 Bit 48 bit (12 BCD digits)
Hex: 55 New CAN-ID BCD coded serial number
The serial number must be BCD coded and right-justified with as many leading zeros as
needed to make 12 BCD digits.
All PC6D on the CANbus will receive the message, but only the PC6D with the serial number
given will react to, and echo the frame with 55h changed to AAh. The PC6D will save the new
setting immediately and then restart itself.
