Battery Life Advisory

The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to
backup the real-time clock and CMOS. The battery should last for the life of the module. The module must be
powered for approximately twenty hours before the battery becomes fully charged. After it is fully charged, the battery
provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is
fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user replaceable.

Ladder logic is required for application of the MVI69-GSC module. Tasks that
must be handled by the ladder logic are module data transfer, special block
handling, and status data receipt. Additionally, a power-up handler may be
needed to handle the initialization of the module’s data and to clear any
processor fault conditions.

The sample ladder logic, on the ProSoft Solutions CD-ROM, is extensively
commented, to provide information on the purpose and function of each rung. For
most applications, the sample ladder will work without modification.

3.3 Adjust the Input and Output Array Sizes (Optional)

The module internal database is divided into two user-configurable areas:

 Read Data
 Write Data.

The Read Data area is moved from the module to the processor, while the Write
Data area is moved from the processor to the module. You can configure the
start register and size of each area. The size of each area you configure must
match the Add-On instruction controller tag array sizes for the R

W

RITEDATA

arrays.

The MVI69-GSC sample program is configured for 600 registers of R
and 600 registers of W

RITEDATA,

which is sufficient for most application. This
topic describes how to configure user data for applications requiring more than
600 registers of ReadData and WriteData.

Important: Because the module pages data in blocks of 200 registers at a time, you must
configure your user data in multiples of 200 registers.
Caution: When you change the array size, RSLogix may reset the tag values to zero. To avoid
data loss, be sure to save your settings before continuing.

5.2 Functional Overview

5.2.1 General Concepts

The following discussion explains several concepts that are important for
understanding module operation.

Module Power Up

On power up the module begins performing the following logical functions:
1 Initialize hardware components

o

Initialize CompactLogix or MicroLogix backplane driver

o

Test and Clear all RAM

o

Initialize the serial communication ports

2 Module configuration
3 Initialize Module Register space

After this initialization procedure is complete, the module will begin
communicating with other devices on the network, depending on the
configuration.

Main Logic Loop

Upon completing the power up configuration process, the module enters an
infinite loop that performs the following functions:

5.2.2 Data Flow between MVI69-GSC Module and CompactLogix
Processor

The following topics describe the flow of data between the two pieces of
hardware (CompactLogix processor and MVI69-GSC module) and other devices
on the network under the module’s different operating modes.

Backplane Data Transfer

The MVI69-GSC module communicates directly over the CompactLogix or
MicroLogix backplane. Data is paged between the module and the CompactLogix
processor across the backplane using the module's input and output images. The
update frequency of the images is determined by the scheduled scan rate
defined by the user for the module and the communication load on the module.
Typical updates are in the range of 2 to 10 milliseconds.

The data is paged between the processor and the module using input and output
image blocks (fixed at 60 words).

This bi-directional transference of data is accomplished by the module filling in
data in the module's input image to send to the processor. Data in the input
image is placed in the Controller Tags in the processor by the ladder logic.

The processor inserts data to the module's output image to transfer to the
module. The module's program extracts the data and places it in the module's
internal database.

MVI69-GSC ♦ CompactLogix or MicroLogix Platform Reference
Generic ASCII Serial Communication Module User Manual

The following illustration shows the data transfer method used to move data
between the CompactLogix processor, the MVI69-GSC module and the network.

All data transferred between the module and the processor over the backplane is
through the input and output images. Ladder logic must be written in the
CompactLogix processor to interface the input and output image data with data
defined in the Controller Tags. All data used by the module is stored in its internal
database. The following illustration shows the layout of the database:

User Manual Generic ASCII Serial Communication Module

Data contained in this database is paged through the input and output images by
coordination of the CompactLogix ladder logic and the MVI69-GSC module's
program. Up to 60 words of data can be transferred from the module to the
processor at a time. Up to 60 words of data can be transferred from the
processor to the module. The read and write block identification codes in each
data block determine the function to be performed or the content of the data
block. The block identification codes used by the module are listed below:

Block Range Descriptions

0 to 127 Normal Data Blocks for Read and Write
9998 Warm-boot control block
9999 Cold-boot control block

Each image has a defined structure depending on the data content and the
function of the data transfer.

Normal Data Transfer

Normal data transfer includes the paging of the user data to and from the
module’s ports and bringing in status data. These data are transferred through
read (input image) and write (output image) blocks. The structure and function of
each block is discussed in the following topics:

Page 76 of 102 ProSoft Technology, Inc.
September 24, 2010

MVI69-GSC ♦ CompactLogix or MicroLogix Platform Reference
Generic ASCII Serial Communication Module User Manual

Block Request from the Processor to the Module

These blocks of data are used to transfer information from the CompactLogix
processor to the module. The structure of the output image used to transfer this
data is shown below:

Word Offset Description

Port 1 0 Block Sequence Number (Read block number as sent by module) (0 to

127)

1 Inter-character delay for this message (milliseconds between

characters)
2 Number of characters to transmit on Port 1 (0 to 50)
3 to 27 Port 1 ASCII character codes to transmit (up to 50 ASCII characters)
Port 2 28 Inter-character delay for this message (milliseconds between

characters)
29 Number of characters to transmit on Port 2 (0 to 50)
30 to 54 Port 2 ASCII character codes to transmit (up to 50 ASCII characters)
55 to 59 Reserved

The Block Sequence Number is that received on the last read block transfer
through the input image on the module. The ladder logic should copy this value
from byte 0 of the input image to byte 0 of output image in the ladder logic. This
must be the last operation performed when constructing the write block. The
module’s program will trigger the process write block function when a new value
is recognized in byte 0 of the output image. If the number of characters to
transmit in the write block is not set to zero (non-zero value in bytes 2 and 29),
this indicates to the module there is data present in the block that needs to be
transmitted. If the selected port is not already busy transmitting data from a
previous write block, the data in the block will be moved to the port’s transmit
buffer and sent out the port as soon as possible.

In order to pace the characters for the write operation, an inter-character delay
value is associated with each write message. For devices that do not buffer
received data, when interfacing with a modem in command mode or when
simulating keyboard or keypad entry, inter-character delays may be required. For
example, if the port is tied to a device that expects input with delays of 200
milliseconds between each character, place the data to send in the write block
output image along with the length and set the inter-character delay byte (bytes 1
and 28) to a value of 200 in the module’s output image in the processor’s ladder
logic program. The message will be transmitted with a 200-millisecond wait
period between each character. Because this delay value is sent from the
processor for each write message, the inter-character delay can be set
independently for each message. For example, when writing AT commands to a
dial-up modem, an inter-character delay of 100 may be required. But when the
modem is in data mode, the inter-character delay can be set to 0. When the
delay is set to 0, the whole packet of data will be placed in the module’s transmit
buffer at one time.

Block Response from the Module to the Processor

These blocks transfer information from the module to the processor. The
structure of the input image used to transfer these data is shown below. The
Block Sequence Number (byte 0) is an index value used to signal to the
processor that a new block is ready for processing. The ladder logic must
recognize a change in this value and process the data encapsulated in the input
image. The block contains the data received on each port and status data. The
two byte values in bytes 1 (port 1 receive length), and 28 (port 2 receive length),
hold the number of characters received on each port to be processed by the
ladder logic. ASCII character code data received on the ports are found starting
at byte 3 and 30 for Port 1 and 2, respectively. The simpler version of the
example ladder logic assumes the number of ASCII characters received on each
port is less than or equal to fifty characters (25 words per port, times 2 characters
per word).

Word Offset Description

0 Block Sequence Number (Bumped each scan by module) (0 to

127)

Port 1 1 Number of characters (0 to 50) in Port 1 receive block (3 to 27). If

the string received on the port is larger than 50 characters,
multiple blocks will be transferred. Any block with a value of -1 in
this field represents the first or continuation block and the block
contains 50 characters of ASCII code data. The last block of data
will contain a positive number in this field that represents the
number of characters in the last block. Status data will be returned
in words 3 to 27 if this word contains a value of 0.

2 Number of characters transmitted (0 to 50) from last block write

for Port 1

3 to 27 Port 1 data received (up to 50 ASCII character codes of data). If

the number of characters received for the port is 0, status data will
be returned in this area.

Port 2 28 Number of characters (0 to 50) in Port 2 receive block (30 to 54).

If the string received on the port is larger than 50 bytes, multiple
blocks will be transferred. Any block with a value of -1 in this field
represents the first of continuation block and the block contains 50
characters of ASCII code data. The last block of data will contain
a positive number in this field that represents the number of
characters in the last block. Status data will be returned in words
30 to 54 if this word contains a value of 0.

29 Number of characters transmitted (0 to 50) from last block write

for Port 2

30 to 54 Port 2 data received (up to 50 ASCII character codes of data). If

the number of characters received for the port is 0, status data will

Generic ASCII Serial Communication Module User Manual

The receive buffer in the module can hold up to 4096 characters. This large size
permits the buffering of a large amount of data before a transfer of the data to the
controller is required. The module buffers incoming ASCII characters in its
receive buffer until one of the user-specified termination conditions is recognized.
The module will then transfer the received terminated string to the controller.

The ladder logic required to properly handle transfer of terminated strings longer
than 50 characters per port is more complex than the simpler version of ladder
logic discussed above. If the terminated string is larger than 50 characters,
multiple blocks will be used to transfer the data to the controller. The first block
will contain a value of -1 in the "Number of Characters Received" data field. This
indicates that there will be more blocks to follow and that the current block
contains 50 ASCII character codes. As long as more than 50 characters remain
in the buffer waiting to be sent to the ladder logic, successive Read Blocks will
continue to show the "Number of Characters Received" as -1. When 50 or fewer
ASCII characters remain in the buffer, the module will send the last block with a
positive number in the length field. The value passed represents the number of
characters present in the data area, which is the last characters of the complete,
terminated string. The ladder logic must recognize the presence of one or more
successive blocks with -1 lengths and then the positive number of the last block
as indication that a single, complete, long string has been completely transferred.

The two byte values at bytes 1 (port 1 transmit count) and 29 (port 2 transmit
count) inform the processor of the number of ASCII characters transferred in the
last write block to the respective port transmit buffers. If a value of zero is
returned in one of these words and data was sent in the last write block, the
ladder logic must re-send the data in the next write block because the port was in
a busy state and could not transmit the last data to be written at the time the
Write Block was receive by the module from the ladder logic. If a non-zero value
is returned in one of these bytes, the value represents the number of ASCII
characters from the last write block that were successfully moved into the port’s
transmit buffer.

The status information transferred in the read block can be used by the
processor to determine the state and "health" of the module and the device(s)
attached to each application port. An important member of the value in the status
object is error word for each port. This value contains the configuration error flags
for each port and the receive buffer overflow error flag.

5.3 Cable Connections

The application ports on the MVI69-GSC module support RS-232, RS-422, and
RS-485 interfaces. Please inspect the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.

Note: When using RS-232 with radio modem applications, some radios or modems require
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the UseCTS parameter to 1.

5.3.1 RS-232 Configuration/Debug Port

This port is physically an RJ45 connection. An RJ45 to DB-9 adapter cable is
included with the module. This port permits a PC based terminal emulation
program to view configuration and status data in the module and to control the
module. The cable for communications on this port is shown in the following
diagram:

5.3.2 RS-232 Application Port(s)

When the RS-232 interface is selected, the use of hardware handshaking
(control and monitoring of modem signal lines) is user definable. If no hardware
handshaking will be used, here are the cable pinouts to connect to the port.

RS-232: Modem Connection (Hardware Handshaking Required)

This type of connection is required between the module and a modem or other
communication device.

The "Use CTS Line" parameter for the port configuration should be set to 'Y' for
most modem applications.

RS-232: Null Modem Connection (Hardware Handshaking)

This type of connection is used when the device connected to the module
requires hardware handshaking (control and monitoring of modem signal lines).

RS-232: Null Modem Connection (No Hardware Handshaking)

This type of connection can be used to connect the module to a computer or field
device communication port.

Note: For most null modem connections where hardware handshaking is not required, the Use
CTS Line parameter should be set to N and no jumper will be required between Pins 7 (RTS) and 8

(CTS) on the connector. If the port is configured with the Use CTS Line set to Y, then a jumper is
required between the RTS and the CTS lines on the port connection.

5.3.3 RS-422

The RS-422 interface requires a single four or five wire cable. The Common
connection is optional, depending on the RS-422 network devices used. The
cable required for this interface is shown below:

5.3.4 RS-485 Application Port(s)

The RS-485 interface requires a single two or three wire cable. The Common
connection is optional, depending on the RS-485 network devices used. The
cable required for this interface is shown below:

Note: Terminating resistors are generally not required on the RS-485 network, unless you are
experiencing communication problems that can be attributed to signal echoes or reflections. In
these cases, installing a 120-ohm terminating resistor between pins 1 and 8 on the module
connector end of the RS-485 line may improve communication quality.

RS-485 and RS-422 Tip

If communication in the RS-422 or RS-485 mode does not work at first, despite
all attempts, try switching termination polarities. Some manufacturers interpret +
and -, or A and B, polarities differently.
