Ok just to clarify, Plant ops are sending messages to office staff via Processbook... Why??? Don't they have email on a PC near them (network acces an issue??), or a phone? If you are stuck with messages in Processbook then I can think of a couple of ways of doing this.

1. Use annotations. Create some dummy tags (Text1, text2, etc) and set them up as Lab entry (manual tags, Pointsource L). Create a text box in your processbook display with a command button next to it. When the operator wants to send a message, they fill in the text box, then click on the command button. Behind the command button is VBA code which writes the text in the textbox to an annotation on tag Text1. The office worker can then view the annotation in a different processbook display (this Processbook would need some VBA code to retrieve the annotation text and display it on screen). Not the easiest thing to set up but it should work.

2. Create an SQL database. Create a processbook display as per suggestion 1, but instead of writing to an annotation, the VB code will write to a database entry. The office worker would then have the database open (with a nice front form) showing the latest set of entries. You would need to setup a DSN entry on the plant ops PC to create the link between Processbook and the SQL database.

3. Buy some plant logbook software (Opralog for example). Not the cheapest option but it would allow the operator to log more than messages to the office staff.

Thats about all I can come up with. Sorry it's not a nice set of easy solutions, but the easiest ones are to give the plant op email, or a phone!
