How to Control NT600S Functions

Reference
Procedure 1. Use the support tool to allocate the PT status control area (PC
Application
This section describes how to control the functions of the NT600S.

Restrictions on allocating words
The PT status control area (PC
listed in the following table.
Symbol C Series PCs
DM Data memory
CH Internal/Special Relay
TIM Timer
CNT Counter
HR Holding Relay
AR Auxiliary Relay
LR Link Relay
Since all the CVM1/CV-series special auxiliary relays are allocated to the system,
they cannot be used for applications not related to the system.
The range of each memory area differs according to the PC type. See "Appendix L
PC Memory Map" (page 291) for more details.
memory.
2. Create a PC program to write control data to the "PT status control bits" of the
PT status control area.

Control timing of PT status control bits
The PT status control area (PC
is only read, and control is only executed, when the contents of the PT status
control area are changed after the NT600S has been started up.
Since control of the NT600S 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.
This example is of the NT600S being used as a warning lamp by using PT status
control bits.

Support Tool Settings
Make the following setting using the support tool.
