MYCROADVANTAGE
Model 320 Driver
MYCROADVANTAGE provides a LIL(320) driver that will communicate with stations on a Local Instrument Link
(LIL). Standard, predefined parameter tables for many LIL products (e.g. Models 351 and 352) are within
MYCROADVANTAGE to simplify configuration. MYCROADVANTAGE release 3.32 does not include a Model
352P/353/354 predefined parameter table. However, when up to three control loops are to be configured in a Model
352P, 353 or 354, use the Model 351 predefined parameter table and configure the ODC blocks in the loops to
channels 8, 13, and 18. This method will work since the loop data in the controller is the same as a 351and is
located at the same relative offsets as in a 351. Loops can also be configured individually. Details on the
configuration can be found the MYCROADVANTAGE user manual. Modbus Driver
MYCROADVANTAGE provides a Modbus driver for communicating with up to 32 stations through a single COM
port. There are a few considerations when communicating with a Model 352P, 353 or 354 using the Modbus driver.
? Loop data is available as integer or floating point. When integer is used, more data is obtained with a single
command, thus improving the communication throughput. When integer data is used, ranges can be scaled
using 3:Linear function MX+B scaling.
? The MODBUS.DAT file must be modified. Under the section [Address Chunk Range], set “UseDefault=0”,
under section [Address Size], set “itChunkSize=48” and “WordChunkSize=60”.
7.1.3 ProcessSuite
RealTime LIL I/O Server
An optional LIL RealTime I/O Server is available to communicate with the Model 320 ICI (Independent Computer
Interface). The 320 communicates over the Local Instrument Link (LIL) with other stations that have the LIL
option boards installed. Refer to the literature provided with the LIL RealTime I/O Server for proper operation.
Optimize LIL performance by using Global Data, especially for data that is updated on each scan such as the
process, setpoint, valve, loop status, and alarm I. Use individual parameter requests only to obtain data not required
frequently (e.g. tuning parameters, range scaling).
Modbus I/O Server
A Modbus I/O Server comes with Process Suite and it can be used to communicate with the controller. Refer to the
Modbus I/O Server instructions for operating details. Certain parameter settings are critical. In the Topic
Definition, use the 584/984 slave type. Set the maximum coil reads to 48 and maximum register reads to 60.
Maximum coil writes can be set to the minimum allowed value of 8 and register writes to 2.
7.1.4 i|ware PC
Modbus OPC Server
The i|ware PC Operator Interface software includes a Modbus OPC server that when connected to the controller can
auto populate its database with the number and type of loops configured in the station. All tag names used in the
OPC database will be the same as listed in this manual.
