Description
NtpClientServerIpAd-
dress
Variable
Read/
write
0
IP address of the NTP server
The NTP client uses the IP address setting to retrieve
the time from an NTP server.
The IP address must be converted to a decimal num-
ber. The calculation is described below the table.
A value of 0 disables the function.
NtpClientServerIpAd-
dressFallback
Variable
Read/
write
0
IP address of the NTP server (fallback)
Optional additional IP address in case the NTP server
cannot be reached via the IP address in the Ntp-
ClientServerIpAddress node.
The IP address must be converted to a decimal num-
ber. The calculation is described below the table.
A value of 0 disables the function.

Method
Write
-
Method for writing the NtpClientServerIpAddress and
NtpClientServerIpAddressFallback nodes.
Use the following formula to convert the IP address to a decimal number. For an IP ad-
dress in the format “A.B.C.D.”:
((A × 256 + B) × 256 + C) × 256 + D = IP address as decimal number
Example for IP address 192.53.103.108:
((192 × 256 + 53) × 256 + 103) × 256 + 108 = 3224725356
10.3.3.1.9 I/O Forcing via OPC UA
The OPC UA client can force output data and simulate input data. In what follows, forcing
output data and simulating input data are referred to together as the Force function. From
the product’s point of view, there must be only one external instance that uses the Force
function. Therefore, the OPC UA client must first obtain a Force ID from the product and
send this Force ID with each Force function call. If the Force ID is incorrect, the product
does not execute the Force function.
The path in the information model is:
Root > Objects > DeviceSet > [device name] > Forcing
The OPC UA client calls the “GetForcingID” method to get a Force ID and enable the
Force function. The OPC UA client can now use the following methods:
• OutputPin2
• OutputPin4
Each of these methods has a Force ID parameter.
The module monitors the Force function with a watchdog timer. If the OPC UA client be-
comes inactive, or the connection via OPC UA is lost, the watchdog timer expires, and
the product switches the Force function off. The watchdog timer has the value 10 s.
