Function List
The following table lists the functions of the FX5-DP-M.
Function
Description
Reference
PROFIBUS-
DPV0
Data exchange function
Performs data exchange of up to 2048 bytes by connecting up to 64 DP-Slaves to one
FX5-DP-M.
Acquisition of diagnostic
information and extended
diagnostic information
Acquires the diagnostic information and the extended diagnostic error information
occurring in DP-Slaves during data exchange using buffer memory.
Global control function
Sends service (SYNC, UNSYNC, FREEZE, UNFREEZE) to each DP-Slave in a group,
and synchronously controls I/O data of DP-Slaves.
PROFIBUS-
DPV1
Acyclic communication
function
Reads/writes data from/to DP-Slaves at a different timing from the data exchange.
Alarm acquisition function
Acquires up to eight items of the alarm or status information occurring in a DP-Slave.
Data swap function
Swaps upper and lower bytes in units of words when I/O data is sent/received.
Data consistency function
Maintains consistency of I/O data of DP-Slaves when it is read/written from/to the buffer
memory.
Output status setting function for CPU stop error
Sets whether to stop or continue the data exchange with DP-Slaves when a CPU stop
error occurs in the CPU module to which the FX5-DP-M is mounted.
Temporarily reserved station specification
function
Temporarily changes a DP-Slave to a reserved station without changing slave parameters
of PROFIBUS Configuration Tool.
