Setting data
■
Description, range, data type
• In safety programs executed by the Safety CPU, only safety devices and safety labels of data types described in the table
can be used.
■
Applicable devices
• In safety programs executed by the Safety CPU, only the following safety devices and constants can be used.
Processing details
■
LD, LDI
• LD is a normally open contact operation start instruction and LDI is a normally closed contact operation start instruction.
These instructions read the on/off information
*1
of the specified bit device, and output it as the operation result.
*1 When a bit of a word device is specified, the instruction outputs on or off according to the status (1 or 0) of the specified bit.
■
AND, ANI
• AND is a normally open contact series connection instruction and ANI is a normally closed contact series connection
instruction. These instructions read the on/off information
*1
of the specified bit device, perform an AND operation with the
previous operation result, and output the operation result.
*1 When a bit of a word device is specified, the instruction outputs on or off according to the status (1 or 0) of the specified bit.
• Note the following when creating or displaying a program using the engineering tool (in ladder edit mode).
■
OR, ORI
• OR is a single normally open contact parallel connection instruction and ORI is a single normally open contact parallel
connection instruction. These instructions read the on/off information
*1
of the specified bit device, perform an OR operation
with the previous operation result, and output the operation result.
*1 When a bit of a word device is specified, the instruction outputs on or off according to the status (1 or 0) of the specified bit.
• Note the following when creating or displaying a program using the engineering tool (in ladder edit mode).
• Specify a bit in a word device in hexadecimal. (For example, specify "D0.0B" for b11 in D0.)
Operation error
There is no operation error.

• Write mode: When the AND and ANI instructions are connected in series, a ladder with up to 24 steps can be created.
• Read mode: When the AND and ANI instructions are connected in series, a ladder with up to 24 steps can be displayed. If there are more than 24 steps, up
to 24 steps are displayed.
• Write mode: Up to 23 OR and ORI instructions can be connected consecutively.
• Read mode: Up to 23 OR and ORI instructions connected consecutively can be displayed. A ladder with more than 23 instructions cannot be displayed
correctly.
