9pin SubD jack:
The CPU has a PROFIBUS/PtP interface with a fix pinout. After an
overall reset the interface is deactivated. By appropriate configura-
tion, the following functions for this interface may be enabled:
n PROFIBUS DP master operation
–
Configuration via PROFIBUS sub module X1 (MPI/DP) with
‘Operation mode’ master in the hardware configuration.
n PROFIBUS DP slave operation
– Configuration via PROFIBUS sub module X1 (MPI/DP) with
‘Operation mode’ slave in the hardware configuration.
n PtP functionality
– Using the PtP functionality the RS485 interface is allowed to
connect via serial point-to-point connection to different source
res. target systems.
– Here the following protocols are supported: ASCII, STX/ETX,
3964R, USS and Modbus-Master (ASCII, RTU).
– The activation of the PtP functionality happens by embedding
the SPEEDBUS.GSD from VIPA in the hardware catalog. After
the installation the CPU may be configured in a PROFIBUS
master system and here the interface may be switched to PtP
communication.
4.2.3 Memory management
The CPU has an integrated memory. Information about the capacity
of the memory may be found at the front of the CPU. The memory is
divided into the following parts:
n Load memory 2Mbyte
n Code memory (50% of the work memory)
n Data memory (50% of the work memory)
n W
ork memory 512kbyte
– There is the possibility to extend the work memory to its max-
imum printed capacity 2Mbyte by means of a MCC memory
extension card.
4.2.4 Storage media slot
n As external storage medium for applications and firmware you
may use a MMC storage module (Multimedia card).
n The VIP
A storage media are pre-formatted with the PC format
FAT16 and can be accessed via a card reader.
n After PowerON respectively an overall reset the CPU checks, if
there is a storage medium with data valid for the CPU.
n Push the memory card into the slot until it snaps in leaded by a
spring mechanism. This ensures contacting.
n By sliding down the sliding mechanism, a just installed memory
card can be protected against drop out.
n To remove, slide the sliding mechanism up again and push the
storage media against the spring pressure until it is unlocked with
a click.
