QB Expert Alpha Controller

Once the file is saved it can be put into the Alpha controller. See section “3.1.4.11 PLC Tab” on page 68.
7.4.1 Invalid Characters
When the logic refers to a specific word in a string file it uses DATA[X], where X is the referenced word. The Alpha
controller does not support the DATA[X] syntax. This must be converted to a number. For example, if the word
referred to is ST14:3.DATA[5] then this must be converted to ST14:3.6 in the file. DATA[5] refers to word six in the
string. The Alpha controller must be given the word number not the DATA[X] number. The X value in DATA[X] is
always one less than the word number referenced in the string.
RSLogix can also substitute one address for a value. When this happens it puts a pound sign (#) in front of the
address. The Alpha controller does not support this pound sign. Find another way to program without using
substitutions.
7.4.2 Predefining String or Integer Files
To use predefined strings or integers, type the string or integer file address and its value before the logic in the
file. There must be a space between the address and the value. For Strings, the value must be encapsulated
within backslash and double quotes. There must be a space after the string or integer value before the first SOR
command or next string or integer.
7.4.3 Applying a Name and Version
To provide a name, put another JSON parameter tag after the logic tag and before the ending brackets. The new
tag is ”701”: “NAME”. There is a 15 character limit to this parameter. If another tag, such as the version number
will be added the name tag must have a comma after it but before the carriage return and line feed (CRLF).
To provide a version, put another JSON parameter tag after the logic or name tag and before the ending brackets.
The new tag is”702”: “VERSION”. There is a 15 character limit to this parameter.
