    • 1st thing is to check is that SB168 is set to do a power up value of 1.   When you look at it in SBs, it is self-explanatory. But I suspect your problem might be something else. cheers, Aus
    • I have set up a Web Server on a V570. Once I view the page within a short time the refresh page is no longer functioning, and the page is not reachable. Have to reboot PLC to reset the connection in order to view page. I also notice the within a few seconds of viewing the page, SB 149 value change to 1 and no long connection. Does anyone and a fix. Thank you  
    • Hi Joe - Getting closer and closer to start my real project coding  I down loaded the 1 EX-RC2Paul 14-7-2018  and 1 EX-RC3Paul 14-7-2018  direct to the units individually. They work fine. even the led's turn red on the IO-PT400'S because my RTD's is not connected yet. EX-RC ID #4-  (make sure it really is ID #4 based on the DIP switches)  - Regarding this point my dip switches it is selected off off on off off off which is suppose to be #3 but when I check my connection the green fall on #4.  The dip switches for unit EX-RC ID  #2 is off on offoffoffoff  and then my Vison 130 ID #1. I would like it to be ID #1,ID#2,ID#3 but it is not working that way. I switched several dip switches to try sort this out. But at least when I test the communication it show green on ID #1,#2,#4  With the two EX-RC1'S sorted -  I have to down load the Main 1Paul 14-7-2018 to the Vision 130 unit directly via canbus network 1  or directly but when I compile before burning it over to the controller  there is three errors and two warnings.  The one is sorted - you duplicated the one Unican send command but the other two errors is as follow: LDR 66 Main Module Out EX-RC1#2 net 3 Before Unican Send High Priority use -/\/of SB201 before new Priority -/\/of SB202 and then I have the same for #4.  with SB 208 I am not sure what this mean or how to correct it.  I just want to ask can you just code for me one MI press button TEST out put activation to the EX-RC1 and do one RTD read coding to see how it must be done on the ladder. I still have to work around the coding you send but need more time to see exactly what you did. Will provide feedback Thank you so much Joe  well appreciated.  Paul            
    • Dear sir,   No, I revert back to 1.18 with system restore.
    • Paul^2, This is a really good example of a complex EX-RC1 application so I'm going to crank through it for the benefit of the forum. Thank you for posting your code! CANbus is a "sending" protocol - you don't read the PT400 inputs from the V130, you send them from the EX-RC1.  The same applies to digital inputs. It's also not the easiest thing in the world to understand, but once you've done one it makes sense.  It's important that you map out your memory first, as described below: Laying things out- EX-RC ID #2- No DI modules IO-PT 4 modules not configured and mapped to local MIs - I configured them as DIN 100 RTDs and  mapped them to local MI 11..26.  Open up the hardware configuration on the RC1 to see what I did.  So - RTD's located in MI 11..26 with be sent to ID #1 V130 MI 201..216.  I chose this address block because there's nothing existing around it. Local O32 ..O95   - V130 outputs O8..O71     This will require four MIs to hold all these bits- V130 MI 20..23 -> RC1 #2 MI 40..43.   I didn't use MI 20 in RC1 because it was already mapped to temperature data. EX-RC ID #4-  (make sure it really is ID #4 based on the DIP switches) No DI modules IO-PT 4 modules partially configured - I configured them as DIN 100 RTDs (alpha = .0385) and  mapped them to local MI 11..14.  RTD's located in MI 11..26 with be sent to ID #1 V130 MI 221..224. Local O32 ..O63   - V130 outputs O72..O103     This will require two MIs to hold all these bits- V130 MI 26..27 -> RC1 #4 MI 110..111. IO-AO6 module - configured 0-10V to local MI 60..65.  The V130 will send  its own MI60..65 to these.    This is a lot to get you head around, but take your time and make your own map of what registers and outputs in the V130 correspond to which I/O in the RC1s.  All your actual control code will be written in the V130. And I may have made a mistake somewhere in here.  I wasn't able to test the configuration.  Let me know if it behaves.
