4.6.4 MODE4
setting
This mode of operation writes analog data to the EW area and reads it from that area.
This mode operates with the prior version of the programming tool and CPU/LPU of the
previous REV (They should be prior to the revisions of the CPU/LPU and programming tool
versions designated for MODE2). If used, the mode will treat one single 8-channel analog
input module as if two 4-channel analog input modules were installed in its place.
To input analog data to the EW area, you must register input addresses and module types with
your user system by using an appropriate programming tool. (To accomplish this, use the
same procedure as used for MODE2. For information on the required manuals and the
relationships between all possible registration numbers and allocated data areas, see Section
4.6.2, “MODE2 setting.”)
y
Module mounting
Any 8-channel analog input module used in this mode is treated as if two conventional
4-channel analog input modules were mounted in a single slot. The figures below shows
examples of mounting an 8-channel AI module and two 4-channel AI modules.
