Connecting NB Series HMI to CP1L Series PLC

[Joel.S]

Hi guys, 

I have been trying to get my PLC and HMI to communicate for a while, I have followed many different tutoirals but keep getting PLC No Response errors.

I am fairly sure I have all the settings right but its still not working

HMI Model - NB5Q-TW01B

PLC - CP1L-EM30T1-D

I have the IP set as 

HMI - 192.168.250.1

PLC - 192.168.250.2 

as per the tutourials I have been following

the nodes set to 1 and 2 repectively and I have transfered all the setting to each unit and rebooted.

Will greatly appericate any help or advice I can get

Thanks

If you could attach your programs, it would be helpful.

I can get my NB to connect with with serial to the CP1L works ok

But no luck with Ethernet to the CP1L

I can connect  and program the NB with Ethernet or USB

I can connect with my CP1L with Ethernet

BUT I need the serial port on the CP1L for communication so I need the NB to connect over Ethernet

NB  192.168.1.160 Node 1 Program with USB

PLC   192.168.1.155 Node 2

and NOTHING

In your PLC settings in CX-Programmer have you set the FINS Node No.?

[Robafe]

Yes I set it to 2

Do I have to set the address or the NB in the PLC or just the Node ?

I have this issue on this site a couple of times hoping to get some more eyes on the problem

SO this is long but interesting..

Here is what i have found out....

I connected the NB to a Brand New CP1L-EM

I put the IP in it and the NB connected. Gone was the (No response from plc)

So i loaded my my program in the new PLC and I can press buttons on the display and see the W bit turn on. Wow progress .......

BUT

I noticed the button I pressed was supposed to put a value into a DM and that didnt happen..

The value was for a screen change.

DM 0000 is for screen change. what ever value you put there the NB will screen change to. (As long as there is a screen setup)

When I checked DM 000 I noticed all values were (0). So I loaded the values from my backup of the original PLC...

Now the NB will NOT CONNECT. Just like the original PLC

There is something in the memory that has been transferred to the new PLC.....

So HOW do I default the PLC back to its original state ??? I tried leaving the power off and  battery disconnected all night and everything is still in there.

Why do I always get the weird stuff ? A tough love leaning process !!!!!

Thanks

From the menu, select PLC > Clear All Memory Errors. You will have to reload the program.

Try reloading only retentive memory and only the memory that will require. In most cases this will be D & H. You can perform a Cross Reference to see what is used in your program. Also, avoid transferring memory from certain locations as they are used for the PLC setup.

How do i only reload D&H from a backup ? as it loads them all when I open the PLC_MEM.MEM

OK now I have a working Network link to the NB

BUT

I have NO ready to send or receive on ether com 1 or 2     A392.05 A392.13

What would lock out both ports for sending and recieving???

I have never had so much weird **** happen.

Both com ports will connect to the CX Programmer no prob.

This is a WTF day.

I went from a working system to dissaster by moving the NB from serial to network

any ideas

Memory does not load automatically when you open the backup file. From the PLC Memory dialog, Monitor ON will show you values currently in the PLC. Monitor OFF will show you values that are saved (if they are indeed saved. It will indicate with a red check mark). You'll need to perform a transfer.

It looks like your serial question is being worked on in a separate thread.

Yes it is because i have been trying to get attention for this problem. Out of pure fustration

 I now have it fixed and I have to tell you the problem was very embarrassing....

But I thank you very much for your help.

This is a great place for less experienced like me to get help
