140 PROSEC T2N

(8) Retentive memory area Designation

This sets and registers the address limits for the auxiliary register

(RW), timer register(T), counter register(C) and data register(D)

which retain pre-power cut data out of the user data when there is

a power cut/power restoration. The limits registered here are

outside the subjects of the user initialization process. For each of

these registers, the limits from the leading address(0) to the

designated address are the retentive memory areas. The power

cut retention limit designations can be registered /monitored on

the system information screen of the programmer.

(9) 10ms Timer Range Setting

This is invalid (setting is not needed.) in the T2N.

(10) Start Mode

This is invalid (setting is not needed.) in the T2N.

(11) Scan Time Setting

This sets and registerd the scan mode (floating/constant). When

no scan time is registered (blank), the mode becomes the floating

scan mode. When a numerical value is set for the scan time, the

mode becomes a constant scan mode which takes that time as

the scan cycle. The setting for the scan cycle is 10-200ms (in

10ms units). The scan time setting can be registered/monitored

on the system information screen of the programmer.

(12) Sub-Program Execution Time

This is invalid (setting is not needed.) in the T2N.

(13) Fixed cycle Timer Interrupt Interval

This sets and registers the interrupt cycle of the time interrupt

program. The setting limits are 5-1000ms (in 5ms units). The

fixed timer interrupt cycle can be registered /monitored on the

system information screen of the programmer.
