Reading and Writing Multiple Tags
You can save communication time by sending a command to read/write more than one tag. The format
for a read command looks like this:
Format: (^R)(Variable ID number)(,) (Count) (^M)
The 'Count' portion of the protocol can be set to allow reading multiple tags.
There are some restrictions for writing. You can write multiple integer tags and ONE string tag. The
string tag MUST be the last tag written. You cannot write more than one string tag. If the string tag is
the first tag written, then all the items listed will be assumed to be part of the string.
Example: ^V5,25,8888,NEW TEXT, STOP,40
This looks like you should write 5 tags beginning with tag 5. Sorry, it won't work. Remember only one
string tag at a time and it must be the last tag. Here is what would happen if the above command string
is sent.
