M800V/M80V Series PLC Programming Manual (1/2)
11 Parameters
11.3 Other Parameters
There are precautions as follows for the setting of the multi-project parameter (device setting).
[Precautions]
(1) Set the number of device points/number of common points in increments of 16 points.
(2) Limit the maximum number of points per bit device to be within 32K.
However, the maximum number of points per internal relay (M)/ link relay (B) device is to be within 60K.
(3) Set the total number of projects which is to be set to 1 device to satisfy the formula below.
(Number of device points set to each project) + (Number of common points) ≤ Maximum number of projects (*1)
(4) Set the total number of device points which is to be set to 1 project to satisfy the formula below.
(Bit device capacity) + (Timer, integrated timer, counter capacity) + (Word device capacity) ≤ 29K word

(5) It is not possible to change the number of device points of project which is already stored in the ladder.

(*1) Refer to "4.3.2 Independent Device among Projects" for the details of maximum number of projects.

11.3.4 Changing Processing Cycle of the High-Speed Ladder by the Parameter

Processing cycle of the high-speed ladder can be changed by the parameter "#1261 set33/bit4".
# No. Item
1261 High-speed ladder
set33/bit4
(PR) execution cycle
Note
(1) When the parameter "#1261 set33/bit4" is set to the default, the processing cycle of the high-speed ladder varies accord-
ing to the NC model or the number of part systems.
