Omron NT31 NT31C manual Installation Method, Method of Use

Using a Memory Unit (-Vj Versions) Section 3-5

Reference: S When a memory unit is mounted, the NT31/NT31C cannot be set to the oper- ating status. On completion of data transmission with a memory unit, always disconnect the memory unit from the NT31/NT31C before starting NT31/NT31C operation.

SMemory units (NT-MF261) can be used in common for the following PT mod- els: NT31, NT31C, NT631, and NT631C (with or without the Vj suffix). One memory unit can store screen data for up to two PTs of different models. How- ever, since the data compatibility is not complete between NT31/NT31C and NT631/NT631C, an error may occur if an attempt is made to read NT631C data with an NT31C. (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 cor- rect since these models have different numbers of colors.

SOne memory unit can store a system program for up to two PTs of different models. In order to transmit a system program from the memory unit to the NT31/NT31C, the system program must be compatible to the target PT model.

SThe 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 written into the NT31/NT31C, make sure that these settings can be adapted to the NT31/NT31C used before transmission.

3-5-1 Installation Method

Install the memory unit (NT-MF261) at the expansion interface connector at the rear of the NT31/NT31C as shown in the figure below (the expansion interface connector is located underneath the note label.).

Mounting screws

3-5-2 Method of Use

As shown in the figure below, a memory unit has two sets of four DIP switches, and the operation is determined by the DIP switches that are set at startup.

OFF

Factory setting is turned all to off.

Note 1. Always confirm that the power to the NT31/NT31C is off before setting the DIP switches.

2. Do not touch the PCB (printed circuit board) directly with bare hands.
