Hello Everyone, I am trying to find some article and watching a youtube video to understand the concept of DeviceNet and can't find enough information. Can someone share any article or your knowledge on this subject?
Please correct me if I am wrong, So far I know DeviceNet is
a communication module can be installed in any slot of PLC rack and the main purpose of this communication module is to connect a PLC controller to remote IO so wiring cost can be reduced.
For example, If I am using one PLC processor to control two production line and these two production lines are far from each other and I don't want to use long wiring to connect devices on production line such as push button, sensors etc back to my IO card of PLC controller, then i can use deviceNet module and install remote IO close to 2nd prodcution line and connect those remote IO with processor through DeviceNet and in that case I will only need one communication cable between devicenet and remote IO and field devices on 2nd production line will connect to my remote IO.
in that case, The remote I/O will be slave and PLC controller will be Master and DeviceNet is the medium which helps PLC controller to send a signal to remote IO.
Please correct me if I get so far right. Now I have a couple of question on that.
1. When I install DeviceNet module to my PLC rack, what kind device/hardware do I need to connect with my Remote IO? or am I going to connect that DeviceNet module directly to remote IO?
2. Let's say If I have more than 2 remote IO at a different location. Do I need 2 DeviceNet module? 1 for each remote IO?
3. How many remote I/O I can connect with my DeviceNet Module?
I am asking this question because let's say I am using processor which allow me to connect maximum of 4 module, instead of using 4 I/O module, Can I connect 4 devicenet module and then connect 4 I/O module to each devicenet so this will allow me to connect 16 remote I/O module.
I would really appreciate if someone can help me to figure this out.
Thank you for reading this post,
Thank you,
