Data storage and send to PC
Specialist
: System edit: Data storage and send to PC
In this menu, the continuous sending of results and signal outputs and the receipt of the
data are defined.
• If stored to the internal hard disk (Flash disk) storage mode “active”), the program
automatically calculates the length of the files that will be created.
When pressing F1 while you are in one of the main menu fields, the free disk space
remaining is displayed.
• When selecting “PC protocol”, the data are output resp. read-in via the serial interface
(
Specialist: Utilities: Service: Environment Configuration
:
Interfaces
). Read-in data will
be shown in the results just like measured values (Parameter S1i at MCS protocol, Ri at
ModBus) (menu
Specialist: System edit: Results)
.
Settings
Results
A mark below the result shows when it is chosen.
When selecting
Results
, a mask appears.
Storage mode
Active / not active: Data will be stored / not stored on the internal hard disk
according to the setting.
It can be chosen between “results” and “signal output”.
The “results” are stored according to the setting below: “Length of data file”. When
“signal outputs” is selected, signals are stored each 60 seconds. One file is
generated for each day and each channel. Max. number of days: 1 month, ring buffer
function. Name of the file:
C:\DATALOG\CHxx\xxdd.dat
| | |
| | dd= day
xx=channel number
Flag
“measure”,
“calibration”
Valid for Modbus protocol only.
These are the numbers of the flags indicating “measure” or “calibration” status. The
Modbus master recognizes by the set flag which operating mode is active at present.
Length of data file Valid for “Storage mode “active“” with “results”, only.
Period of time until terminating a measured value file. At the end of the period
defined, the file is closed and a new file is opened. From the length of the file and the
number of results to be stored, the program calculates the size of the file to be
created.
Caution
: Upon failure of the computer (e.g. power failure) all data from a
measurement file that is not yet completed will be lost.
Period (Cycle)
Cycle time of data storage and transmission to serial interface.
Device address
Device address (0..200) for identification for external data acquisition systems.
PC Protocol
Modbus RTU (Slave)
: MCS100E functions like a ModBus Slave.
Modbus RTU (Master): MCS100E functions like a ModBus Master.
MCS only on request
: MCS100E sends data to the serial interface on request, only.
MCS100E is continuously ready for receiving data.
MCS on request and in cycles
: MCS100E sends data on request and in cycles to the
serial interface. MCS100E is continuously ready for receiving data.
Modbus Definition:
The menu that is presented is used for setting the ModBus
parameters. This requires detailed knowledge of the ModBus structure.
During data transmission the address offset is always added to the start register,
resp. only subtracted when data are received, if the start register > address offset.
Modbus Test (Data exchange)
: This menu is designed for service purposes, only, to
test the ModBus communication. The data sent and received are presented as
hexadecimals.
When making changes in the selection of the results or in the length of the data
file: Move the cursor once over the field “length of data file” to trigger a new
calculation.
Status bars 1 and 2 are always stored to archive, independent of active/
inactive data storage (
).
