Acyclic Receive
Description
In addition to "Cyclic Receive", it is possible to transfer further data acyclically to
SIMOCODE pro via PROFIBUS DP. With the "Acyclic receive" function block, you can
specify which acyclic information from the PROFIBUS DP will be further processed in
SIMOCODE pro. With the "Acyclic receive" function block, you can specify which information
will be further processed in SIMOCODE pro.
The "Acyclic receive" function blocks consist of:
● Eight bits each (byte 0 and byte 1 for binary information)
● One word (= two bytes, byte 2 to 3 for an analog value, freely parameterizable).
Overall there are three "Acyclic receive" function blocks (0, 1, 2/3)
The following schematic shows the "Acyclic receive" function blocks:
Figure 4-70 Function schematic of acyclic receive data
Acyclic data are transferred only on request.
The information (4 bytes) can be found in data record 202. This data record can be written
by every master (PLC or PC) that supports the acyclic services of PROFIBUS DPV1.
Connection monitoring is activated every time the data record is received. The content of the
data record is deleted after a 5-second time-out has elapsed.
