RIO Limits
To follow has a utilization descriptive of remote and redundant CPU's in LC700. For each master
CPU is possible to have up to 6 RIO’s slave, and to each RIO had:
120 Words (240 bytes) of analog inputs, for example:
• 120 inputs for PT100 (15 X M-402) or;
• 120 inputs 4 to 20 mA (15 X M-401R) or;
• 60 inputs through FB700.
120 Words (240 bytes) of analog outputs, for example:
• 120 outputs 4 to 20 mA (30 X M-501) or;
• 60 outputs through FB700.
The digital inputs and outputs are limited for the total number in the CPU.
For the updating of redundant CPU’s, where it is necessary to use remotes, prevail the same rule.
Whenever the necessity goes bigger than these limits, the user will need to divide in more remotes.
