Description
For remote I/O communications, the user can select and allocate the
following I/O data, for which there are 15 patterns when combined:
I/O data for control
-
- Status data
- General status data
Refer to Section 3-2.
For remote I/O communications, the user can select and allocate the
following I/O data, for which there are 16 patterns when combined:
- I/O data for control
- Status data
- General status data
- Output monitors
Refer to Section 3-2.
For remote I/O communications, the user can select and allocate the
following I/O data, for which there are 16 patterns when combined:
- I/O data for control
- Status data
General status data
-
- Output monitors
Refer to Section 3-2.
The present, bottom, and peak values of the network power voltage can
be recorded in the DST1. A monitor voltage (default setting: 11 V) can
be set in the DST1 and the Network Power Voltage Drop Flag in the
general status data will turn ON when the voltage drops below the set
monitor value.
The total ON time (unit: 0.1 hrs) of the DST1's internal circuit power can
be calculated and recorded. A monitor value can be set in the DST1
and the Unit Maintenance Flag in the general status data will turn ON
when the total time reaches the set monitor value.
The user can assign and record a name or comment for every DST1
(up to 32 characters). These terminal names/comments can be read
and written.
characters each) and record it in the DST1. The connected device can
be checked for each I/O contact, allowing faulty devices to be identified
during remote maintenance.
The date on which maintenance was last performed can be written in
the DST1. This means that the timing for future maintenance can be
judged more easily.
This function is used to detect whether the I/O power is ON. When the
I/O power supply is turned OFF, the Safety Input Power Status Flag or
Safety Output Power Status Flag in the general status data turns ON.
Contact operation counters are used to count the number of times each
input or output contact changes from OFF to ON (maximum resolution
of 50 Hz) and record the total values in the DST1.
The total ON time for each I/O contact can be calculated (unit: s) and
recorded in the DST1. Monitor values can be set in the DST1, and
when the set number of operations is reached, the Connected
Component Maintenance Flag in the general status data turns ON.
The operation time monitor can measure the time from when an output
contact goes ON to when the input contact goes ON (unit: ms) and
record the time in the DST1.
