Download and edit problems usually have some basis in a bad communications/privilege setup. Here are some basic settings to check to make sure that comms are set up correctly.
1. Check the MEMORY PROTECT KEY. It should be OFF.
2. Determine if you are communicating through the front port (channel 0) or a DH+ port (S5/SR5).
If you are connected to the front port, check the following:Cable connection - make sure it is tight and that you are using the correct cable.Use the LIST functions from the front panel of the PLC-3 (SHIFT, then LIST) or from the online menu (F1-Processor Functions, F2-LIST) to set the timeout and privilege 0.Select Module Status.Select the 1775-S5 or -SR5.Select CHAN 0. Make sure the CHANNEL TIMEOUT is set to 0. If not, change it to 0.Select PRIVILEGES. Make sure privilege 0 (write to the system area) is in the list of enabled privileges. If it is not in the list, press 0<Enter> to enable it.
If you are connected to a DH+ port on an S5 or SR5, check the following:Cable connection - make sure it is tight and that you are using the correct cable.Use the LIST functions from the front panel of the PLC-3 (SHIFT, then LIST) or from the online menu (F1-Processor Functions, F2-LIST) to set the timeout and privilege 0.Select Module Status.Select the 1775-S5 or -SR5.Select CHANNEL 4.Select DH/DH+ CONFIG.Check options 6 (ACCEPT UPLOAD/DOWNLOAD) and 7 (ACCEPT WRITES). Make sure there is an asterisk '*' next to each one, indicating that that option is enabled. If not, press 6<Enter> and/or 7<Enter> to toggle the options on.Select PRIVILEGES. Make sure privilege 0 (write to the system area) is in the list of enabled privileges. If it is not in the list, press 0<Enter> to enable it.
The LIST functions and privileges are discussed in publication 1775-6.5.5, "PLC-3 Family I/O Scanner Communication-Adapter Module -- User Manual", which is found on the A-B web site at http://www.ab.com/manuals/cp/1775655.pdf.
