To whom it may concern, 

The update for print # -0622 request is completed. (See attached) 

The CAT V Ethernet cable for EWEB module is connected to switch.

Hello Scot, 

The 1756-EWEB module was installed in the Solenoid Local PLC chassis at slot 8. This probably will involve changes in drawing B000000900-0622. 

The module was connected in the PLC chassis but we still need the Ethernet connection between the EWEB module and the Switch. Can you provide the Ethernet cable for this connection? 

Thanks, 
Pablo

Hi Ruben, 

We have a spare PLC EWEB module ready for installation into the Solenoid PLC. 

This will allow us to synchronize the Time stamping between the following systems: 
Torus PLC, Torus cRIO's, Solenoid PLC, and Solenoid cRIO's. 

The EWEB module gets its clock from NTP time server, same as cRIO's. Once the IP address is assigned it is plug and play, no development/coding required. 

Best Regards, 

Nick
