Processing details
■
LD, LDI
• The LD instruction is the NO contact operation start instruction, and the LDI instruction is the NC contact operation start
instruction. These instructions capture the ON/OFF information
*1
of the specified device, and use the result as the
operation result.
*1 When bits of word devices are specified, devices turn ON/OFF by the 1/0 status of the specified bit.
■
AND, ANI
• The AND instruction is NO contact series connection instruction and the ANI instruction is NC contact series connection
instruction. These instructions capture the ON/OFF information
*1
of the specified bit device, AND with the operation result
so far, and use the result as the operation result.
*1 When bits of word devices are specified, devices turn ON/OFF by the 1/0 status of the specified bit.
• There is no limitation to the number of series contacts. Any number of contacts can use this instructions consecutively.
• Output to other coils through contacts after the OUT instruction is called cascade output, and these outputs can be
repeated any number of times as long as their order is correct.
■
OR, ORI
• The OR instruction is NO contact parallel connection and the ORI instruction is NC contact parallel connection. These
instructions capture the ON/OFF information
*1
of the specified device, OR with the operation result so far, and use the
result as the operation result.
*1 When bits of word devices are specified, devices turn ON/OFF by the 1/0 status of the specified bit.
• These instructions are connected in parallel from the step with this instruction to the previous step with the LD and LDI
instruction.
• There is no limitation in the number of parallel connections.
• When bits of word devices are specified, bits are specified in hexadecimal. (For example, b11 of D0 is
specified by "D0.B".)
Operation error
There is no operation error.
