Limitations of the modules' data exchange rates

Introduction
Evaluation of input and
output factors
98
There are two options for connecting remote peripheral modules: via
JX3-BN-CAN using the JX2 system bus protocol, or via JX3-BN-ETH using
the Ethernet system bus protocol. JX3 modules of a JX3 station exchange
data either with a JC-120MC controller, or with bus node modules
JX3-BN-CAN and JX3-BN-ETH. The maximum number of input and output
data and of JX3 peripheral modules in a JX3 system is limited.
The following table lists the factors for input and output data.
 Add the input factor of all modules used and calculate the aggregated input
factor.
Add the output factor of all modules used and calculate the aggregated

output factor.
 Compare the aggregated factor for inputs/outputs with the allowed
maximum factor:
where n <= 16.
