Re: PGM-J Programmer Manual


Dear Mr. John Hay,




Thank you for visiting our website, and for your interest in our products.




This falls into the category; “STRANGE, BUT TRUE…”


The PGM-J and its big brother PGM-JR2 are both still being manufactured. The PGM-J was originally designed for use with the Hitachi “J” series. Around the time Hitachi offered the “E” series as the upgrade replacement to the “J”, the PGM-JR2 was added to the line-up. Since that time, the “E” was replaced by the “EB”, which was again superceded by the “EC” series. During all this time, Hitachi has intended that each successive model be a relatively easy upgrade to the previous releases. For that reason, the original hand-held programmers have been retained. Today, with the addition of a “protocol converter cable” (CNPG-15), either programmer can be used on the EC’s serial port.




Here is where it gets weird. Somewhere along this journey, Hitachi stopped making the manual for the PGM-J. They still make the unit – just not the manual. The PGM-JR2 and its manual are both still made.




So, here are your options. The keystrokes of the PGM-JR2 are identical to that of the PGM-J. There are many things the bigger unit can do that the smaller unit cannot. But the basic functions, timer value changes and so forth, are the same. So try and lay your hands on NJI-049A(X) Operations Manual for the PGM-JR2. Just ignore the sections that do not apply.




Your second option (again, strange but true..) is a manual created by Reliance Electric. The Hitachi PGM-J was relabeled and sold by Reliance Electric as their 45C950. They created their own manual, based on the one from Hitachi (I think it is better). Its part number is J-3803.




We have both the NJI-049A(X) and the J-3803 manuals in stock and would be happy to quote you on these.




Hope this helps.

Replying to:

Dear Sir/Madam,




I am struggling to find a manual to use an Hitachi PGMJ hand held programmer for an Hitachi E64HTP plc. I know they were built years ago, but ours is still going strong and we need to tweak the program to suite our facility.




Any help would be very much appreciated.




Thank you.
