binary mode will determine whether the contents of the addressed word are
taken as a BCD or binary value.)
There are differences in the instruction operands for BCD mode and binary
mode, however, so check and understand the differences between the BCD
and binary modes before changing the timer/counter PV refresh mode.
1. The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units support only
the BCD mode.
2. When the mnemonic is monitored from the Programming Console for CS1-
H, CJ1-H, CJ1M, or CS1D CPU Units manufactured on or before 31 May
2002 with the timer/counter PV refresh mode set to binary mode, the mne-
monic of the binary is displayed as the mnemonic or the BCD instruction
(example: TIMX #0000 &16 is displayed as TIM #0000 &16), but opera-
tions are performed in binary mode.
3. The PV refresh mode can be selected with CX-Programmer Ver 3.0 only.
Mode selection is not supported by CX-Programmer Ver 2.1 or lower, or
the Programming Consoles.
4. CX-Programmer Ver. 2.1 or lower cannot read user programs for the CPU
Unit containing binary-mode instructions, but it can read those set using
BCD-mode instructions.

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.
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.)
