SATELLITE SAVE/RESTORE
The data which is entered on the following ECC/WCC II screens
is stored in the memory of the satellite controllers and is not stored
in the CPU (personal computer):
1) Analog Inputs
2) Control Outputs
3) Analog Outputs
4) Trend Logs
5) Logic Switches
6) TUC
However, you have the option of saving the information which is
in the satellite controllers on a disk in the Central Processing Unit
(CPU) to allow you to have a back-up copy of the satellite data. We
strongly encourage you to do this to avoid the possibility of having
to manually re-enter satellite data.
The satellite data may be saved on a disk which is in the CPU
(personal computer) located at the building being controlled, or if
you have our remote communications software, you may save this
information on a disk in a remote computer which communicates
with the CPU over telephone lines.
The information for up to 240 satellite controllers may be saved
on a hard disk, or information for up to 10 satellite controllers may
be saved on one 5¼” fl oppy disk or 20 satellites on a 3½” disk.
Before the system saves the data on the disk, it checks to see if data
for the particular satellite already exists on the disk. If it does, the
information which is already on the disk is put in a back-up fi le, and
the new information is saved in a new data fi le. Therefore, when
you are saving the information from the satellites for the fi rst time,
it is possible to get the data from 20 satellite controllers on one 5¼”
fl oppy disk. However, the next time you try and save the data, you
will get a “disk full” message due to the system making the back-
up fi les. If your system has more than 10 satellites controllers, and
your CPU has dual fl oppy 5¼” disk drives, then we recommend
saving satellites 1-10 on one disk, 11-20 on the next disk, etc.
An ECC/WCC II system requires a System Disk, a Data disk, and
a Satellite Backup Disk(s). We recommend keeping a backup copy
of these disks, especially if you have a CPU with a hard disk drive.
See the Section in this manual titled, “Initiating the System” for
additional information on making backup disks.
System Disk
The system disk has the computer programs, or “code”, on it
which enables the CPU to operate as an energy management
and temperature control system. This disk stays in drive A or B
(depending on the version of software) on dual disk systems
(dual fl oppy disk drives). If your system has a hard disk drive, the
information from this disk is loaded onto the hard disk (drive C).
Data Disk
The information which is entered on the screens in the “Overview”
and “Central Unit” categories of the Main Menu is automatically
saved on the data disk. This disk stays in drive A or B (depending
on the version of software) on dual disk systems. If your system
has a hard disk drive, the information is automatically saved on the
hard disk (drive C).
Satellite Backup Disk(s)
Data from the satellite controllers is copied onto the satellite
backup disk. If you have a dual disk drive system, the satellite
backup disk(s) is not kept in the CPU, but should be kept in a safe,
dry, dirt and dust free location. If your system has a hard disk drive,
this information is kept on the hard disk (drive C).
Change Path
The system will automatically save the information from the
satellite controllers on the same drive as the Data Disk which is
shown on the heading of this screen after “Satellite File Directory.”
If you would like to save the data to a different disk drive, follow
these instructions:
Access the System Parameters Screen and sign on by
entering your password. You must have a level 3 access
code to perform this operation.
Return to the Main Menu and place the cursor over the
words “Save/Restore to Disk” and press
. The
following screen should appear:
---------------------------------------------
--SATELLITE <--> DISK Operations -- Satellite
File Directory: a:\
S(save to disk), R(restore from disk), C(change
path) or E(exit)?
---------------------------------------------
Since you would like to “change the path” of where the
data is to be saved, press
