Np IRstuff!
So if the display showed 9.234pF and 1.5Kohms, I had 9.4385e-10 and 3450 respectively.
If there wasn't any resistance to measure, I'd still have an average of 3kOhms and a 9.285e-10 instead of the 2.85pf shown on display. With every trigger, only the digits after the decimal point...
Thanks all for your help.
Answering IRstuff, whenever I didn't have any resistance to be measured, there was still a value in the buffer and consequently shown in the Rs value. Also the capacitance read through the block didn't match those physically and read by the LCR meter...
While I was...
Thanks once again John for your reply. I do not think that it is using MSB or LSB format. For RS232 communication there is Receive_P2P block which receives the length of the sent info as UInt and the data as an Array of Bytes.
The above list is the first bytes in the tempbuffer where it reads...
Thank you John for your help.
This is the format in which the Chroma sends back the values:
0,9.517396e-10,4.050937e+03
When using Hercules to communicate directly with Chroma with the above port parameters, the values are correct and when doing a closed loop RS232 communication from PC...
Hi,
I require some help regarding RS232 communication using TIA portal v15, CPU 1511-1 PN and a CM PtP RS232 BA module. I am relatively new to PLC programming. Kindly refer to the links to SCL program block, Trace, Ladder and defined operands jpegs.
I am sending GPIB commands (like those...
