What are the features of OMRON’s PLCs compared to the S7 series?
Thread Content
It seems that PLCs now account for the majority of Siemens’ market share. The ORMON series is used in some heat transfer systems in chemical enterprises in the Jiangsu and Zhejiang regions. What are the advantages of this system compared to the S7? Or rather, which is better or worse? Could someone who uses it frequently share their thoughts?
The ORMON series is one tier lower than the Mitsubishi series, not to mention when compared to Siemens
I guess price factors play a big role. The quality should be more or less the same. Another key point is that OMRON’s technology is relatively conservative.
All functions can be implemented. To compare prices, service, and hardware reliability, the cost of spare parts also needs to be taken into account
The S7 series generally uses the Profibus protocol from PI, while Omron’s PLCs use the DeviceNet protocol for communication between master and slave stations. The communication protocols between the master and slave stations are different.
Omron’s products lack openness. The protocol is also not universal
Omron is a Japanese product; it would be good to have some resistance against it
