5.1 Diagnostic options
The following tools are available for diagnostics:
● Ping server:
Using the "ping" program that exists on all standard computers with a Windows operating
system from Microsoft, you can check whether a CP 243-1 can be reached at all at a
specified IP address.
● STEP 7 Micro/WIN 32:
Under the entry "Information ..." in the "PLC" menu, you can see general the information
about your S7-200 system. This also includes information that shows you which modules
are connected to your S7-200 system. After you double-click on the module "CP 243-1
INTERNET" in the module overview, a window appears with the following specific
information about your CP 243-1:
– General module information (module type and versions used)
– TCP/IP address parameters (IP address, subnet mask, IP address of the gateway and
the MAC address). When a configuration error occurs and a restart is performed
afterwards with the BOOTP/DHCP mechanism, the values shown here are not valid.
This same applies when the user program has not completed at least one cycle.
– Status messages
– Information on the embedding of the CP 243-1 in the address area of the S7-200 CPU
– Configuration and statuses of the S7 channels
– Error messages
– Configuration and statuses of the IT functions (FTP server, FTP client, HTTP server
and e-mail client)
● Reading the SM memory area:
During run time, information specific to the CP 243-1 can also be read and processed by
an S7-200 user program from the SM area currently being used by the CP (refer to the
example in section E-mail tags (Page 55)). When global errors occur on a CP 243-1, the
rele
vant error identifiers are located in this area. The locations where the information can
be found are described below.
