Communications Specifications
For a Host Link, RS-232C
* When using an NT-AL001, the specifications are as follows.
• RS-232C cable: Max. 2 m
• RS-422A cable: Total length 500 m max.
Programming Console function Executes functions equivalent to those of a C200H-PRO27-E Programming Console
for CPM1, CPM1A, CPM2A, CPM2C, CQM1 (-EV1 only), CQM1H, C200HX/HG/
HE(-Z)E, and SRM1 (C02-V2 only) PLCs.
Executes functions as a Programming Console for CS/CJ-series PLC.
Device Monitor function The Device Monitor function can be used to change the PLC’s operating mode, read/
change words in the PLC’s data areas, and display the PLC’s error log. Compatible
PLCs include the CPM1, CPM1A, CPM2A, CPM2C, CQM1, CQM1H, C200HX/HG/
HE(-Z)E, SRM1, and CS/CJ-series PLCs.
Mathematical function Up to 256 calculation expressions can be registered along with the screen data. The
mathematical function reads the required data from numeral memory tables or host
words, executes the registered calculations, and writes the results.
Arithmetic operators, logic operators, bit operators, and comparative operators can be
used.
