*1 LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2 The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
The range of each memory area differs according to the PLC type. Appen-
dix H Special Characters (page 163) for more details.
1. Use the support tool to allocate the PT status control area (PLC ® PT) to
the PLC memory.
2. Create a PLC 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 (PLC ® PT) is not read when the NT11 starts
up. It is only read, and control is only executed, when the contents of the
PT status control area are changed after the NT11 has been started up.
Since control of the NT11 statuses is executed after the bits corresponding
to the PT status control bits have changed, to execute control again the
corresponding bits must be specified again.
The example below shows how the PT status control bits are used to execute
daily report printing.
• Setting at the support tool
Perform the following setting with the support tool.
PT status control area allocated word: CIO/IR 0118
• PLC program
Create the following PLC ladder program:
00110
00111
• Program operation
1. When CIO/IR 00110 comes ON, the daily report printing bit (bit 4) of the
PT status control area is set to "1". The status of bits other than bit 4 re-
mains unchanged.
When bit 4 is set to "1", the daily report is printed.
