MELSEC System Q |
|
|
 |
HIGHLY DEVELOPED CONTROL
The Q series can utilize a multiple PLC system where multiple high-performance CPUs are loaded on the same main base to manage I/O
and intelligent function modules CPU-by-CPU in a control system. In the multiple PLC system, you can choose CPUs according to your
application. With the multi-CPU system, inter-CPU communication uses two methods, cyclic communication, which uses automatic
refreshing for periodic communication, and transient communication, which uses dedicated instructions for communications. This system
allows the sequence control and data processing that were conventionally performed by a single CPU to be shared by multiple dedicated
CPUs, improving speed and performance in the whole system and expanding its application range. |

ANALOG I/O MODULE |
|
|
 |
The analog input modules convert analog process signals, for example pressure, flow or fill level, linearly into digital values, which are further processed by theQCPU. Up to 8 channels per module (Q68AD_) and up to 512 channels per system (QCPU) Calculation of average value over the time or measurement cycles can be configured Potential isolation between process and control by means of an optocoupler is standard
