6.9 Communication with HIMA OPC Server (BUSCOM)
The F 8627X communicates with an OPC server via the non safety related BUSCOM vari-
ables.
6.9.1 F 8627X configuration
The F 8627X is configured in ELOP II and via DIP switches.
In ELOP II, the resource name under ELOP II must have eight characters, the last two of which
must be numbers. The numbers must be unique to avoid collisions while determining the com-
munication module's IP address (see Chapter 5.1).
While configuring the communication with a HIMA OPC server, pay particular attention to the
Passive mode (see Chapter 6.9.1.1 to Chapter 6.9.1.3).
6.9.1.1 Passive mode disabled (switch S1/8 "ON")
The token passing between the F 8627X and the HIMA OPC servers is active.
• If the Passive Mode is disabled on the F 8627X, it must also be disabled on the
HIMA OPC s+ervers.
• With HIPRO-S, safety-related communication must be set up such that
each PES
has configured a safety-related data exchange with all other PES (i.e. exchange of
dummy data if no other user data are exchanged). The direction of the data
exchange can be freely selected.
This procedure is used because all Ethernet nodes must be known in each PES
within SafeEthernet to ensure communication within the network (token passing).
6.9.1.2 Passive mode enabled (switch S1/8 "OFF")
In this mode the F 8627X's behavior is passive and HIMA OPC server polls it in certain time
intervals.
The token passing between the F 8627X and the HIMA OPC servers is disabled.
• The Passive mode may be only activated on a F 8627X, if HIMA OPC server also
supports it (HIMA OPC server version 3.2.0 and higher).
• The Passive Mode can also be activated, if safety-related communication for the
F 8627X module is configured.
Note The F 8627X OPC communication is only possible with a HIMA OPC
server.
Note If HIPRO S DIRECT mode is active (switch 1/7 "ON"), switch S1/8
"passive mode" no longer influences communication. For this reason,
"passive mode" must also be activated on the HIMA OPC servers.
