Internet PLC Forum

I am sure this has been discussed before, but why does the RTC cause my HMI to time out from time to time.  I read in the doc's a bent pin can cause this, but I checked this several times and it continues to do so.  Any help would be appreciated.  

BTW, I have a MD888+ and this didn't happen before it was installed with the RTC.  I need this  in case of power outage.

I think you might be a bit mixed up, when you look at 32bit data the least significant bit is all the way to the right.  So when you break up a 32bit variable into two 16bit pieces of data with the GET16HIGH function, that returns the data from bit 8 to bit 31, that is the upper part of the 32bit variable.  When you store your data in the DM memory, you need to place the upper part of the 32bit data one place to the right of the lower part.  For example:

DM[1]=A
DM[2]=GET16HIGH(A)

then let the HMI look at DM[1] with the field setup as a 32 bit datatype and you should see the correct result.

I will be checking back here in awhile, if you still are having trouble, just reply to this message.
 

I just purchased an E10Relay, I was wondering if a 25.2VAC transformer would work in place of the mentioned 24VAC.  I have the former in my parts bin and I was just wondering if it was outside the parameter's of the unit?

Also, I didn't buy the starter kit, thinking that the Trilogi 5.3 software would program the unit, is this correct?  I have the 485 converter so that isn't an issue.

Many thanks in advance.
