In case one of the settings of the previous step is incorrect, change to the cor-
rect value and power OFF and ON the system.
Once the network is re-started with the new settings, check that the Option
Board LED indicators indicate proper operation: If everything is correctly con-
figured, both the MS (Module Status) LED and the NS (Network Status) LED
will be Green. Please refer to section 5-1 Troubleshooting Using the LED Indi-
cators for troubleshooting any configuration errors if the LED indicators are
displaying a different pattern.
Tip In case of any errors during configuring the network, please refer to Section 5
Troubleshooting and Maintenance on page 31.
When the CompoNet network is operating properly, optionally the Master Unit
provides the possibility to register the Slave Units.
Registration Tables are used to register Slave Units that are intended to par-
ticipate at particular node addresses to verify that they actually are participat-
ing. At the same time, they prevent unregistered Slave Units and Slave Units
of the wrong models from participating in the network.
Perform the registration sequence of the Master Unit.
The registration sequence for a slave of non-default Input and/or Output size
(2 words in/ 2 words out) requires a manual adaptation of the EDS file.
Perform the following steps to resolve this issue:
Determine the input and output size of the assembly chosen. This information
can be found in Appendix C-3 Assembly Object (Class 0x04) on page 55.
As example, take for instance you have selected Extended Control IO and
Multi-function input monitor (assemblies 101 and 153) by selecting P046
(Default Connection Path) = 5. The resulting output size is 8 bytes and input
size is 10 bytes.
Adapt the non-default sizes in the EDS file of the Unit you are configuring. The
data to change can be found in the "[CompoNet_IO]" part.
For the example, the [CompoNet_IO] part will look like this (notice the length
is in words instead of bytes):
[CompoNet_IO]
CompoNet_Input_Info =
2,
5;
CompoNet_Output_Info =
2,
4;
Install the EDS file in CX-Integrator and perform the registration sequence of
the Master Unit. Confirm the Registration table shows the correct input and
output size.
If these steps are omitted, the CRM21 Master will fail to connect to the Slave
at startup, indicating both error d5 (Verification error: non-existent Slave Unit)
and d6 (Verification error: unregistered Slave Unit).
