P0700 – CAN PROTOCOL
Range: 1 = CANopen Default: 2
2 = DeviceNet
Properties: CFG
Access groups via HMI: NET
Description:
It allows selecting the desired protocol for the CAN interface. If this parameter is changed, the change takes
effect only if the CAN interface is not powered, it is in auto-baud or after the equipment is switched off and on
again.
P0701 – CAN ADDRESS
Range: 0 to 127 Default: 63
Properties: CFG
Access groups via HMI: NET
Description:
It allows programming the address used for the CAN communication. It is necessary that each element of the
network has an address different from the others. The valid addresses for this parameter depend on the
protocol programmed in P0700:
P0700 = 1 (CANopen) → valid addresses: 1 to 127.
P0700 = 2 (DeviceNet) → valid addresses: 0 to 63.
If this parameter is changed, the change takes effect only if the CAN interface is not powered, auto-baud or
after the equipment is switched off and on again.
P0702 – CAN BAUD RATE
Range: 0 = 1 Mbit/s /
Autobaud
Default: 0
1 = 800 Kbit/s /
Autobaud
2 = 500 Kbit/s
3 = 250 Kbit/s
4 = 125 Kbit/s
5 = 100 Kbit/s /
Autobaud
6 = 50 Kbit/s /
Autobaud
7 = 20 Kbit/s /
Autobaud
8 = 10 Kbit/s /
Autobaud
Properties: CFG
Access groups via HMI: NET
Description:
It allows programming the desired baud rate for the CAN interface, in bits per second. This rate must be the
same for all the devices connected to the network. The supported bauld rates for the device depend on the
protocol programmed in the parameter P0700:
P0700 = 1 (CANopen): It is possible to use any rate specified in this parameter, but it does not have the
automatic baud rate detection function –
autobaud
.
P0700 = 2 (DeviceNet): only the 500, 250 and 125 Kbit/s rates are supported. Other options will enable the
automatic baud rate detection function –
autobaud
.
If this parameter is changed, the change takes effect only if the CAN interface is not powered or after the
equipment is switched off and on again.
After a successful detection, the baud rate parameter (P0702) changes automatically to the detected rate. In
order to execute the autobaud function again, it is necessary to change the parameter P0702 to one of the
‘
Autobaud’
options.
