JX3 station - Maximum

Engineering steps
Jetter AG
The following devices are not taken into account when calculating the
aggregated input/output factor:
 Controller JC-120MC
 Bus node JX3-BN-ETH
 Bus node JX3-BN-CAN
 Power supply module JX3-PS1
The table below lists the maximum allowed number of modules and the
aggregated factor of input data and output data.
Maximum 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-120MC. 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:
2 JX3-DI16 and 8 JX3-AI4 modules are connected to a controller
JC-120MC. 2 JX3-DI16 with input factor 0 makes 0; 8 JX3-AI4 with input
factor 0 makes 0 => aggregated factor is 0.

... the aggregated input factor

... the aggregated output factor

... the number of peripheral
modules is 16, ...
If one of the three values has been exceeded, a new JX3 station must be
added. For this, apply a bus node, e.g. a JX3-BN-ETH.
