I'm trying to re-write some software to access a PLC's (Koyo DL205) 8 channel analogue input by using it's 100MBIT DL205 ethernet base controller (H2-EBC100).
I have been told that I need my computer to be setup with an IP of 10.0.1.1. However, looking at the code that has previously been written for communicating with this controller, the controller itself appears to have an IP of 10.1.0.100.
I really have no clue about ip addresses. I've been trying to ping the controller all afternoon, with little success. So I've been trying to ping a laptop on the same network with my original ip. The laptop's ip is 192.168.1.101 and my desktop is 192.168.1.100 (and the wireless router is 192.168.1.1). I can ping both laptop and router ok. If I change my ip to 192.168.1.200 I can still ping both. However, if I change my ip to 192.168.2.100 I can't ping anything. If I then change the laptop to 192.168.2.101, I can ping the laptop, but not the router.
So, thinking now that I must keep the first three parts of my ip the same as the ethernet controller, I change my desktop ip to 10.1.0.1 (believing that the controller's ip is 10.1.0.100). But I still cannot ping it.
I'm now at a bit of a loss as to exactly what my desktop ip address should be and how to find out the ip of the ethernet controller. Do you think a problem might be because I'm going through my managed router (which has it's own ip address)? Is there any way to search for this controller another way?
