Please also enter the command PING <IP address> at the DOS
prompt to check whether the NETLink
®
Gateway can also be
accessed physically via the network.
Q: The setting dialog boxes are not appearing in the Simatic Man-
ager:
A: Please note that after initial installation the NETLink-S7-NET
driver must be added to the PG/PC interfaces interfaces (except
with Windows 7 operating systems).
Make sure you had administrator rights during installation. Re-
boot your PC after installation if prompted to do so.
You need at least version 5.1 of the Simatic Manager.
Q: If I set the NETLink
®
Gateway to auto baud in the PG/PC
interface and try to go online, the active LED lights up briefly be-
fore a message appears telling me that the bus parameters cannot
be determined.
A: Either the CPU used does not support the cyclic transmission
of bus parameters (disabled via parameterization or function does
not exist), or the CPU is so busy with general communication
tasks that the lower-priority bus parameter frame is transmitted
too infrequently and cannot be detected by the NETLink
®
Gateway.
Please deactivate the auto baud functionality in the NETLink-S7-
NET driver (PG/PC interface) and set the correct baud rate and the
correct profile.
Q: If I mix RFC1006 connections and connections via the STEP7
driver, the link sometimes breaks off or error messages appear
saying that it is not possible to establish a link.
A: For communication with S7-300 modules it may be necessary
to parameterize the communication resources.
The user can influence the allocation of existing ‘connection re-
sources’ under object properties of the CPU in the hardware con-
figuration.
Q: The variables from my S7 200 CPU are not updated in my
WINCC project.
