Common Industrial Protocol (Cip) Devicenet & Ethernet/Ip; Data Types Used With Cip; Profibus Dp - Watlow EZ-ZONE PM User Manual

cation does not dictate which register should be high
or low order Watlow provides the user the ability to
swap this order (Setup Page, Com Menu) from the
default low/high [lohi] to high/low [ hilo] .
Note:
With the release of firmware revision 7.00 and
above new functions where introduced into this
product line. With the introduction of these new
functions there was a reorganization of Modbus
registers. Notice in the column identified as Modbus
the reference to Map 1 and Map 2 registers for each
of the various parameters. If the new functions,
namely; Math, Linearization, Process Value,
Real Time Clock and the Special Output Function
are to be used than use Map 2 Modbus registers.
If the new functions of this product line are not
to be used, Map 1 (legacy PM controls) Modbus reg-
isters will be sufficient. The Modbus register map-
ping [map] can be changed in the Setup Page un-
der the [Com] Menu. This setting will apply across
the control.
It should also be noted that some of the cells in the
Modbus column contain wording pertaining to an off-
set. Several parameters in the control contain more
than one instance; such as, profiles (4), alarms (4),
analog inputs (2), etc... The Modbus register shown
always represents instance one. Take for an example
the Alarm Silence parameter found in the Setup
Page under the Alarm menu. Instance one of Map 1
is shown as address 1490 and +50 is identified as the
offset to the next instance. If there was a desire to
read or write to instance 3 simply add 100 to 1490 to
find its address, in this case, the instance 3 address
for Alarm Silence is 1590.
The Modbus communications instance can be either 1
or 2 depending on the part number.
Instance 1:
PM _ _ _ _ _ - [1] _ _ _ _ _ _
Instance 2:
PM _ _ _ _ _ - [2] _ _ _ _ _ _

Common Industrial Protocol (CIP)
DeviceNet & Ethernet/IP
Both DeviceNet and EtherNet/IP use open object
based programming tools and use the same address-
ing scheme. In the following menu pages notice the
column header identified as CIP. There you will find
the Class, Instance and Attribute in hexadecimal,
(decimal in parenthesis) which makes up the address-
ing for both protocols.

The CIP communications instance will always be in-
stance 2.

Data Types Used with CIP

uint = Unsigned 16 bit integer
int = Signed 16-bit
dint = Signed 32-bits, long
real = Float, IEEE 754 32-bit
string = ASCII, 8 bits per character
sint = Signed 8 bits , byte

Profibus DP

To accomodate for Profibus DP addressing the follow-
ing menus contain a column identified as Profibus
Index. Data types used in conjunction with Profibus
DP can be found in the table below.
The Profibus communications instance will always be
instance 2.
Word = Unsigned 16 bit
INT = Signed 16-bit Integer
dint = Signed 32-bit Integer
REAL = Float, IEEE 754 32-bit
CHAR = ASCII, 8 bits per character
BYTE = 8 bits
