Changing the Timer/Counter PV Refresh Mode Section 6-4
6-4-2 Functional Specifications
Note When the mnemonic is monitored from the Programming Console for CS1-H/
CJ1-H CPU Units manufactured on or before 31 May 2002 with the timer/
counter PV refresh mode set to binary mode, the mnemonic of the binary is
displayed as the mnemonic or the BCD instruction (example: TIMX #0000
&16 is displayed as TIM #0000 &16), but operations are performed in binary
mode.
Checking the CPU Unit Lot Number
1,2,3... 1. The lot number is printed on the bottom of the front panel (CS Series) or
the right corner of the top of the Unit (CJ Series), and is comprised of the
last two digits of the year, the month, and the day, in that order, as shown
in the following diagram.
Example: 020601 (Manufactured on 1 June 2002.)
2. Check which mode is selected by putting the CX-Programmer online,
opening the I/O Table Window, and selecting Unit Information - CPU
Unit. The lot No. will be displayed in the same format as shown in the
above diagram, i.e., comprised of the last two digits of the year, the month,
and the day, in that order.
