Section 1-3
CS1/CJ1W-PRM21
PROFIBUS DP-V1 DTM
In addition to the PROFIBUS DP functions, the CS1/CJ1W-PRM21 PROFI-
BUS DP-V1 DTM provides:
• A communication channel to the user to change a remote slave device
address. This channel has its own user interface.
• Communication channels to facilitate data transfer, PROFIBUS DP-V1
MSAC1 acyclic message transfer between a PROFIBUS DP-V1 slave
device DTM and the physical slave device.
C200HW-PRM21 DTM
The C200HW-PRM21 DTM allows configuration of the C200HW-PRM21
PROFIBUS DP Master Unit. This predecessor of the CS1/CJ1W-PRM21 can
be used on existing C200H PLC CPU Systems as well as CS1 PLC Systems,
except for the CS1D.
The C200HW-PRM21 DTM consist of three parts:
• The Settings DTM, which handles the settings for the C200HW-PRM21
PROFIBUS DP Master Unit, including the bus parameters settings, and
the I/O data mappings.
• The Monitoring DTM, to handle the Unit’s status monitoring. The DTM’s
user interface displays the Master status and Slave status.
• The communication DTM, providing the interface between the two DTMs
mentioned above and the serial communication driver, to the C200HW-
PRM21 PROFIBUS DP Master Unit.
Note
1.
This Operation Manual does not contain a detailed description of the
C200HW-PRM21 Unit, only a description of the DTM. For more details on
the C200HW-PRM21 refer to C200H-series PROFIBUS DP Master Units
Operation Manual (W349-E2-
@
).
2.
The C200HW-PRM21 Unit and DTM do not support PROFIBUS DP-V1.
Generic Slave DTM
The Generic Slave DTM allows the handling of classic GSD files of up to GSD
revision 3 within CX-Profibus. Upon allocating a slave device, for which only a
GSD file is available to a Master Unit in the network, this DTM will be invoked.
This DTM consists of two parts:
• The Settings DTM will provide the user interface to display the device’s
information and the selectable values, as defined in the GSD. After mak-
ing the necessary configuration settings, and saving them, these will be
transferred to the Master DTM.
• The monitoring DTM will provide a diagnostics interface to the user, allow-
ing him to check the Slave’s status. This DTM obtains the necessary infor-
mation from the PROFIBUS Master Unit’s monitoring DTM.
Note
The Generic Slave DTM provides parameter settings related to PROFIBUS
DP-V1. However, it does not support PROFIBUS DP-V1 communication.
Downloading the
Configuration
After setting up the configuration, it must be downloaded to the PROFIBUS
Master Unit. The type of serial connection to use for downloading, depends on
the Unit:
• CS1/CJ1W-PRM21: Connection to the Unit is achieved through the serial
port of the PLC CPU, using CX-Server. CX-Server also allows routing the
download through multiple systems, if supported by these systems. The
CS1/CJ1W-PRM21 does not support message routing.
• C200HW-PRM21: Connection to the C200HW-PRM21 is achieved
through a serial RS-232c Connection between one of the PC’s Serial
COM Ports and the dedicated configuration connector at the front of the
