Note: Memory Cassettes created using the CPU Unit can be read to the CPU Unit, regardless of which model is used, however the following points
must be taken into consideration.
1. When using a Memory Cassette created with a V1 CPU Unit for a Pre-V1 CPU Unit, use the Memory Cassette within the ranges for the
Pre-V1 CPU Unit's timers, holding timers, counters, weekly timers, calendar timers, and displays.
2. When using a Memory Cassette created with a CPU Unit with 20 I/O points for a CPU Unit with 10 I/O points, use only up to 6 inputs and
4 outputs for the I/O bit area.

Battery Unit 10 years min. Battery 
life (at 25° C)
The program and parameter settings are backed up in the CPU Unit's 
internal EEPROM and will not be lost. Use the Battery Unit to prevent 
loss of calendar/clock, holding bits, holding timer present values, counter 
present values, and other data when the power is turned OFF for an 
extended time (for 2 days or more at 25° C). This data is otherwise backed 
up using RAM and a super-capacitor.

ZEN Support Software Runs on Windows 95, 
98, 2000, ME, XP or 
NT 4.0.
Specifically designed for the ZEN (CD-ROM). ZEN-SOFT01-V3
