Introduction
Intelligent module access instructions are used to read or write data between the CPU module and a maximum of seven
intelligent modules while the CPU module is running or when the CPU module is stopped.
Upgrade Information
Upgraded CPU modules can use the intelligent module access instructions. Applicable CPU modules and system program
version are shown in the table below. For the procedure to confirm the system program version of the CPU module, see
page 29-1.
Use WindLDR ver. 4.50 or higher to program the intelligent module access instructions.
Intelligent Module Access Overview
The Run Access Read instruction reads data from the designated address in the intelligent module and stores the read data
to the designated operand while the CPU module is running. The Run Access Write instruction writes data from the desig-
nated operand to the designated address in the intelligent module while the CPU module is running.
The Stop Access Read instruction reads data from the designated address in the intelligent module and stores the read data
to the designated operand when the CPU module is stopped. The Stop Access Write instruction writes data from the desig-
nated operand to the designated address in the intelligent module when the CPU module is stopped.

While the CPU module is running
and the input is on, RUNA READ is
executed to read data from the
intelligent module, and RUNA
WRITE to write data to the intelli-
gent module.

When the CPU module is stopped,
STPA READ is executed to read
data from the intelligent module,
and STPA WRITE to write data to
the intelligent module.
