Mnemonic Input Example
Use the following procedure to convert a step ladder program created in mne-
monics or uploaded into a ladder diagram. This procedure is possible only when
ITEM200 (the Mnemonic Flag) of the step ladder program (block model 301) is
set to 0. The step ladder program cannot be converted to mnemonic code if
ITEM200 is set to 1.
Select Convert Mnemonics to Ladder from the Manipulate Ladder Menu or
click the icon. The mnemonics will be converted to a ladder diagram.
Note 1. When uploading a step ladder program (block model 301) from a unit Ver.
2.00 or earlier Loop Control Unit, ITEM200 (the Mnemonic Flag) will be set
to 1 automatically. Change this setting to ITEM200=1 when the program is
converted to ladder diagram format.
2. No syntax check will be made on step ladder programs being created in
mnemonics. Therefore, when a step ladder program is converted into a lad-
der program, the instruction blocks may be illegal.
3. If ITEM200 (the Mnemonic Flag) is set to 0, the program will be disas-
sembled automatically (mnemonic to ladder diagram conversion) during the
upload operation when it is uploaded from the Loop Controller.
Take the following steps to display the cross-references for a step ladder pro-
gram. The cross-references show the instructions with their contact addresses
and mnemonic row numbers in the Step Ladder Bock for each block address.
Note Before displaying the cross-references, convert the ladder diagram into mne-
monics, otherwise no cross-references will be displayed.
1. Select Convert Ladder to Mnemonics from the Manipulate Ladder Menu
or click the Refresh Button while the mnemonics are displayed, and then
click the OK Button.
