Connections SSK13/ :
The assignment on the network module or on the
COMPAX-S corresponds to the Interbus-S - standard.
Possible connections with SSK13/..:
!
Network module X7 (OUT)
→
Network module X6 (IN)
!
Network module X7 (OUT)
→
COMPAX-S X5 (IN)
!
COMPAX-S X7 (OUT)
→
Network module X6 (IN)
!
COMPAX-S X7 (OUT)
→
COMPAX-S X5 (IN)
!
IIPC / SPS
→
COMPAX-S X5 (IN)
!
IIPC / SPS
→
Network module X6 (IN)
If there is a direct power supply by COMPAX-M, the
connection is made to the component block
EAM5/01 instead of to the network module.
1.5 PDU Length
64 Byte
Maximum message length through the PCP channel.
1.6 Communication
Option F2 includes the Interbus-S communications
software PCP 1.5 (Peripherals Communication Protocol),
which allows it to transmit, in addition to cyclical process
data, acyclic parameters (2 Byte data channel).
The following services are available:
Context Management
!
Initiate Start communication connection
!
Abort Quit communication connection
!
Reject Reject a service
VFD Support
!
Status Reading the device and user status
!
Identify Reading the manufacturer, type and version
Variables Access
!
Read Reading a variable (parameter)
♦

1.3 Identification code (ID-
Code)
When P196 Bit 0...2 < "4"
227 (0xE3)
When P196 Bit 0...2 = "4"
(Operation without acyclic channel = without PCP-
communication)
