TIWAY I Primitives Supported by S5 PIM
B-2
S5 UniLink Adapter Installation and Operation
TIWAY I Primitives provide a uniform command level access to industrial
devices through the TIWAY I Industrial Local Area Network. This section
describes the set of primitives supported by the S5 UniLink Adapter*.
The S5 PIM supports the following exception field values.
Request: None
Response: LLLL 00 PP DDDD
Symbol Value Definition
PP Request primitive code that contains the exception.
DDDD 0000 The primitive code is not implemented in the S5 PIM.
0001 There is no corresponding S5 memory type that maps to the
TT type supplied.
0002 Data element location (specified by TT) is out of range (see
Note).
0003 Primitive has excess data unit bytes.
0004 Primitive has insufficient data unit bytes.
0005 The number of information bytes received does not match the
number of bytes specified in the field length.
000A The attached CP 525 module fails to respond.
000E Primitive not valid for the specified data type (TT).
0010 The number of locations requested exceeds the maximum
allowed (see Note).
0011 The number assigned to a data acquisition block or record is
not within the supported block or record range.
0012 The block or record number requested has not been defined.
0013 The number of data bytes in the requested blocks or records
exceeds maximum number of bytes allowed by the primitive.
0017 The attached device did not respond properly.
0019 The resulting data element location formed by the starting
address, plus the number of data elements to access, is out of
range specified by TT.
001A Communications has not been established with the attached
device.
001D The number of locations to access is zero (NNNN = 0).
0024 An illegal IEEE floating-point value (an IEEE NaN,
Not-a-Number) exists in a primitive write request.
80DD An exception was generated by the CP 525 module, and its
byte value is contained in the DD field.
