Process Data; Modbus Tcp - Danfoss MCA 122 Modbus TCP Operating Instructions Manual

Parameters

5.2.3 12-2* Process Data

12-21 Process Data Config Write
Range:
[[0 - 9] PCD read 0 - 9] Configuration of readable process
In POWERLINK this parameter is read only. Same applies
for 12-22 Process Data Config Read, 12-23 Process Data
Config Write Size and 12-24 Process Data Config Read Size.
12-22 Process Data Config Read
Range:
[[0 - 9] PCD read 0 - 9] Configuration of readable process
5 5
12-27 Primary Master
Option: Function:
This parameter control allows fast swapping of masters.
If this parameter is set 0.0.0.0, the first masters that
access the frequency converter locks the interface for
other masters.
If the communication is lost, the frequency converter
will hold the connection for 30 s before a second
master can take control.
By setting [0] IP address of first Master and setting [1] IP
address of second Master, only these two masters can
control the frequency converter and the second master
does not have to wait 30 s to take control.
Only one master may control the frequency converter
at any time, otherwise the frequency converter might
malfunction.
[0] IP address of first Master.
*
[1] IP address of second Master.
12-28 Store Data Values
Option:
[0] Off
*
[1] Store All
set-ups
12-29 Store Always
Option: Function:
Activates function that always stores received
parameter data in non-volatile memory (EEPROM).
[0] Off
*
[1] On

MCA 122 Modbus TCP
Function:
data.
Function:
data.
Function:
This parameter activates a function that stores
all parameter values in the non-volatile
memory (EEPROM) thus retaining parameter
values at power-down.
The parameter returns to "Off".
The store function is inactive.
All parameter values are stored in the non-
volatile memory, in all 5 set-ups.
