Sending escape character from MicroLogix serial port configured in ASCII protocol - PLCS.net

iknowsomeplc · November 6th, 2003, 06:54 AM

Hi all,

My requirement is to send out escape character ( and also enter , line feed characters)from MicroLogix serial port configured in ASCII protocol , but I couldn't enter this characters in my string file. Is this possible? Anybody have any idea?

I don't know about MicroLogix, but in CompactLogix you can enter non-printable characters bij entering a dollarsign followed by a two-digit hexadecimal number, eg. $0A for linefeed, $0D for newline and $1B for escape.

If you're using an SLC, you can do the same by entering a backslash followed by the hex code: /0A, /0D and /1B.

Kind regards,

Check the setting for the CH0. Maybe they are used as termination
characters.

Jean Pierre's backslash method should work on a MicroLogix since it's part of the SLC family.

http://www.asciitable.com has a list of hex codes for the non-printable characters.
