How to Control NT11S Functions
This section describes how to control the functions of the NT11S.

Restrictions on allocating words
The PT status control area (PC
®
PT) can be allocated to the PC memory areas
listed in the following table.

The range of each memory area differs according to the PC type. See “Appendix H
PC Memory Map” (page 160 of the APPENDICES) for more details.
Procedure 1.
Use the support tool to allocate the PT status control area (PC
®
PT) to the PC
memory.
2.
Create a PC program to write control data to the “PT status control bits” of the
PT status control area.
S
Control timing of PT status control bits
The PT status control area (PC
®
PT) is not read when the NT11S starts up. It is
only read, and control is only executed, when the contents of the PT status con-
trol area are changed after the NT11S has been started up.
Since control of the NT11S statuses is executed after the bits corresponding to
the PT status control bits have changed, to execute control again the corre-
sponding bits must be specified again.
