Engineering of a JX3 Station Equipped With a Bus Node JX3-BN-ETH
The following JX3 modules are not to be taken into account when calculating
the aggregated input/output factor:
 Controller JC-3xx
 Bus node JX3-BN-ETH
 Power supply module JX3-PS1
The table below lists the maximum allowed number of modules and
inputs/outputs.
Max. number of
peripheral modules
16
To engineer a JX3 Station, proceed as follows:
Step
1 Do not exceed the maximum number of 16 modules per JX3 station.
2 Calculate the aggregated input factor by adding the input factor per
module.
Example:
2 JX3-DI16 and 8 JX3-AI4 modules are connected to a controller JC-3xx.
2 JX3-DI16 with input factor 4 makes 8; 8 JX3-AI4 with input factor
10 makes 80 => aggregated factor is 88.
3 Calculate the aggregated output factor by adding the output factor per
module.
Example:
10 JX3-AO4 with output factor 8 makes 80; 4 JX3-MIX2 with output
factor 6 makes 24 => aggregated factor is 104 and exceeds the
maximum allowed output factor of 88.

the aggregated input factor makes
88,
the aggregated output factor makes
88,
the number of peripheral modules
is 16,
If the aggregated input/output factor of your peripheral module configuration
exceeds 88, you need to redesign your configuration. Add, for instance, a bus
node JX3-BN-ETH to build up an additional JX3 station where you can place
the excess inputs/outputs.
