Hi Phil,
Here are copies of the tape from the level transducers. There may be some questions we want to ask Jake as well, for instance at what level does the HWS high level alarm go off?

Good Morning Jason
Last Wednesday we installed the new network switch and exterminated/tested the cabling.
On Friday we scanned and recording all IP addresses on the SCADA network and are updating the control system block diagram with this information as well as log in information.
We also completed the Ethernet data exchange (EGD) map and are turning this into an excel document for future reference.
On Friday we also programmed the handshake routine between all the PLC’s at the WWTP though this logic was not placed in service at that time as it was late in the day.
Tomorrow we will be on site to test network throughput and to place the handshake alarm logic into operation. (We wanted to be there today, but it is a typical Monday)
We will also plan to remove the transfer pump disable buttons from the HMI at that time if possible.
Thanks,
Troy B. Collison
