Using a Memory Unit (NT631/NT631C without V1)
Section 3-6
3-6 Using a Memory Unit (NT631/NT631C without V1)
This section discusses the using of a memory unit when the system program for
NT631/NT631C with V1 is installed to the NT631/NT631C (NT631-ST211
j
-E/
NT631-ST141
j
-E/NT631C-ST151

-E) without V1.
Reference In this case, the function and use of the memory unit are the same as ones for the
NT631/NT631C without V1. (The system program transmission by using a
memory unit cannot be processed.)
By installing a memory unit (NT-MF261) on the NT631/NT631C, the screen data in
the NT631/NT631C can be recorded (backed up) in the memory unit.
In addition, the screen data in the memory unit can be automatically read into the
NT631/NT631C when it starts up. This means that 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 NT631/NT631C screen data can be
changed simply by changing the memory unit, without connecting to the Support
Tool.
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 NT631/NT631C
or reset it.
- Do not touch the PCB (printed circuit board) with bare hands.
Reference - When a memory unit is mounted, the NT631/NT631C cannot be set to the oper-
ating status. On completion of data transmission with a memory unit, always
disconnect the memory unit from the NT631/NT631C before starting
NT631/NT631C operation.
- Memory units (NT-MF261) can be used in common for the following PT models:
NT31, NT31C, NT631, NT631C (with and without V1). One memory unit can
store screen data for up to two PTs of different models. However, since the data
compatibility is not complete between NT31/NT31C and NT631/NT631C, the
data of NT631 cannot be used in NT31C without putting it through a conversion
(the data must be converted using the Support Tool).
Note also that although there is data compatibility between the NT31 and
NT31C, and between the NT631 and NT631C, the display may not be correct
since these models have different numbers of colors.
The screen data for the NT631/NT631C with V1 cannot be used if a system pro-
gram is for the NT631/NT631C without V1.
- The statuses of memory switch settings and system settings can be recorded to
the memory unit besides screen data. When the data in the memory unit is writ-
ten into the NT631/NT631C, make sure that these settings can be adapted to
the NT631/NT631C used before transmission.
