3.2 Take the CANopen field bus into operation
If you are putting the field bus into operation for the first time, you will first
have to set up the PLC programming environment
Chapter 5 “Connecting the PLC to the gateway using CODESYS”, page
53.
Generally speaking, the following steps must be carried out when commis-
sioning the gateway for the first time:
1.
Open or create the project in the PLC programming environment.
2.
Install the appropriate EDS files in the PLC programming tool.
3.
Select the field bus master in the PLC programming environment (target
system) and set a Baud rate, e.g., 250 kBaud.
4.
Select the gateway as a field bus module
5.
Select the XN300 slice modules; this step is skipped when using a proj-
ect-specific EDS file.
6.
Configure the gateway's and the XN300 modules' parameters in the PLC
programming tool.
The I/O slice modules' parameters will be stored in the object dictionary.
If you are using analog modules, observe the following requirements:
•
If default mapping (index 0x6401/x) is used for analog modules, PDO-
based data transmission for these I/O slice modules must be enabled by
setting the value of object index 0x6423, subindex 0 to TRUE
“7.15.3 Analog Input Global Interrupt Enable (Object 0x6423)”, page
187.
•
Regulate the bus load on the CAN field bus
The following procedure is recommended in order to prevent the XN-
312-GW-CAN gateway from generating a heavy load on the CAN field
bus:
•
Use internal module filters; please consult manual "XN300 slice
modules", MN050002-EN".
•
If using the default mapping (index 0x6401/x), a transmission filter
can be configured for each individual payload data object (SDO
objects: AI_DELTA_VALUE, index 0x6426/x).
When this filter is configured, the gateway will update and transmit
the corresponding value only if this value is different from the last
transmitted value by more than the configured delta
“7.14.6 Analog Input Interrupt Delta Unsigned (Object 0x6426)”,
page 170.
•
By setting an inhibit time or selecting a synchronous transmission
type, TPDO properties can be configured in such a way as to avoid
impermissible bus loads
