The CS1/CJ1W-PRM21 PROFIBUS Master Units perform an interface func-
tion between a PROFIBUS network and the CS1/CJ1 PLC CPU. On both
sides of the interface different formats for data and data storages are used.
To ensure that I/O data transferred through the interface can be used on both
sides of the interface without additional formatting, the CS1/CJ1W-PRM21
PROFIBUS Master Units perform the necessary data formatting. This ensures
that I/O data in the PLC CPU memory can be processed by standard PLC
Instructions, and that the I/O data transferred to / from the PROFIBUS DP
slaves over the network is compliant with the PROFIBUS DP definitions.
The table below lists the I/O data formats supported by both the PROFIBUS
network and PLC CPU.
Size PROFIBUS DP
[bytes]
1 Supported.
Data is transmitted on a byte-by-byte
basis.
2 Supported.
Data is transmitted on a Most-Signifi-
cant-Byte First basis.
4 Supported.
Data is transmitted on a Most-Signifi-
cant-Byte First basis.
4 Supported.
Data is transmitted on a Most-Signifi-
cant-Byte First basis.
-- Supported.
Length of string is fixed by I/O configura-
tion. Data is transmitted on a left-to-right
basis (i.e. first character is transmitted
first).
-- Supported.
Length of string is fixed by I/O configura-
tion. Data is transmitted on a left-to-right
basis (i.e. first character is transmitted
first).
7 Supported.
Date/Time format contains absolute time
with respect to start of century. Date/
Time is coded in individual bytes.
6 Supported.
Time of day format contains time since
midnight.
6 Supported.
Time difference format is the same as
Time of day format, but contains a time
difference.
Section 3-5
CS/CJ-series PLC
Not supported
Minimum is 16-bit words. Two bytes will
be formatted in one word. Words con-
taining odd bytes will be padded with
zeros.
Supported.
Single 16-bit integers are transferred to
memory words in PLC memory.
Supported.
Data is stored with the Least-Significant-
Word at the lowest address.
Supported.
Data is stored with the Least-Significant-
Word at the lowest address.
Supported.
First characters are stored at the lowest
address. String is padded with a zero
byte or a zero word, depending on the
number of characters.
Supported.
First bytes are stored at the lowest
address. String is padded with a zero
byte or a zero word, depending on the
number of characters.
Not Supported.
Date/Time format is transferred to PLC
memory as string of words.
Not Supported.
Time of day format is transferred to PLC
memory as string of words.
Not Supported.
Time difference format is transferred to
PLC memory as string of words.
