3-5 Using a Memory Unit(NT31/NT31C with V1)
This section discusses the using of a memory unit when the system program for
NT31/NT31C with V1 is installed to the NT31/NT31C (NT31-ST121
j
-EV1
/NT31C-ST141
j
-EV1) with V1.
Reference: Depending on the PT model and the system program which is installed, the func-
tion and using method of memory unit varies as follows.
PT Model System Program Function of Memory Unit
Without “V1”
Conventional memory unit function. (Refer to

(System programs can not be transmitted using
memory unit.)

By installing a memory unit (NT-MF261) on the NT31/NT31C, the screen data in
the NT31/NT31C can be recorded (backed up) in the memory unit.
In addition, the screen data in the memory unit can be automatically read into the
NT31/NT31C when it starts up. This means that system program and screen data
can be changed easily at the operation site without connecting to the Support Tool.
The data in the memory unit is retained without backup by a battery or other
means.
In systems where there are frequent setup changes, by preparing a number of
memory units in advance and recording screen data in them in accordance with
the control performed in each case, the NT31/NT31C screen data can be changed
simply by installing the memory unit, without connecting to the Support Tool.
In addition, even if NT31/NT31C is replaced, the previous status can be main-
tained simply by installing the memory unit that retains the system program and
screen data of the previous NT31/NT31C.
By using the following combinations, data can be stored (backed up) to a memory
unit.
S
Screen data for two PTs.
S
System program for two PTs.
S
System program and screen data for one PT.
One memory unit can store the screen data for two PTs.
Notice - Make sure that the power supply to the PT is OFF before connecting or discon-
necting a memory unit.
After mounting a memory unit, be sure to tighten its two screws.
- During data transmission, do not turn off the power supply to the NT31/NT31C or
reset it.
- Do not touch the PCB (printed circuit board) with bare hands.
