Sequence Instructions

Functions

LD, LDI

(1)LD is an N/O contact operation start instruction, and LDI is an N/C contact operation start instruction. Each of them imports the ON/OFF data of the specified device and uses it as an operation result.

AND, ANI

(1)AND is an N/O contact series connection instruction, and ANI is an N/C contact series connection instruction. Each of them imports the ON/OFF data of the specified device, ANDs it with the previous operation result, and uses the resultant value as an operation result.

(2)There are no restrictions on the use of AND and ANI, but there are the following conditions in the ladder mode.

1)Write......... When contacts are connected in series by AND or ANI, a ladder of up to 21 contacts can be created.

2)Read......... When contacts are connected in series by AND or ANI, a ladder of up to 24 contacts can be displayed. If the ladder has more than 24 contacts, up to 24 contacts are displayed.

OR, ORI

(1)OR is an N/O contact parallel connection instruction, and ORI is an N/C contact parallel connection instruction. Each of them imports the ON/OFF data of the specified device, ORs it with the previous operation result, and uses the resultant value as an operation result.

(2)There are no restrictions on the use of OR and ORI, but there are the following conditions in the ladder mode.

1)Write......... A ladder of up to 23 contacts connected consecutively by OR or ORI can be created.

2)Read......... A ladder of up to 23 contacts connected consecutively by OR or ORI can be displayed. If the ladder has more than 23 contacts, it cannot be displayed properly.

Execution Conditions

Executed every scan independently of the device ON/OFF and preceding operation result.
