CAUTION
1. 24-V Power Supplies Required for UL Certification
PCON controllers (PCON-C/CG, CY, SE, PL/PO) are UL-certified, where one condition for the
certification is to use Class 2 24-V power supplies.
Accordingly, you must use Class 2 power supplies for both the input power supply and I/O power
supply for your equipment incorporating the PCON, if the equipment as a whole must be UL-certified.
2. Use Environment
PCON controllers can be used in an environment of pollution degree 2 or equivalent.
3. PC Software and Teaching Pendant Models
New functions have been added to the entire PCON controller series.
To support these new features, the communication protocol has been changed to the general
Modbus (Modbus-compliant) mode. As a result, the existing PC software programs and teaching
pendants compatible with RCP2 controllers can no longer be used.
If you are using this controller, use a compatible PC software program and/or teaching pendant
selected from the following models.
Model Remarks
PC software RCM-101-***
Teaching pendant CON-T, RCM-T
Simple teaching pendant RCM-E
Data setting unit RCM-P
All are compatible with existing RCP2
controllers
Touch panel display RCM-PM-01 Not compatible with RCP2 controllers
4. Recommendation for Backing up Latest Data
This product uses nonvolatile memory to store the position table and parameters. Normally the
memory will retain the stored data even after the power is disconnected. However, the data may be
lost if the nonvolatile memory becomes faulty.
(We strongly recommend that the latest position table and parameter data be backed up so that the
data can be restored quickly in the event of power failure, or when the controller must be replaced for
a given reason.)
The data can be backed up using the following methods:
[1] Save to a CD or FD from the PC software.
[2] Hand write the position table and parameter table on paper.
