Interface Panel. The interface panel provides various ports for

connecting the controller to the marking system equipment. The

Marker port, USB port, and Aux Axis port are used to connect the

marking head, system PC, and optional auxiliary axes, respectively.

I/O control signals may be connected to the I/O port and the TTL

Input port. (See I/O Control Signals.) RS-232 and TCP/IP

communications may be connected to the PC and routed to the

marker through the USB port. (See Host Communications.)

TCP/IP Interface. The Ethernet (TCP/IP) interface is most often

used with host computers communicating over a local area network

(LAN). With this type of interface, you may use either Extended

Protocol or Programmable Protocol.

The Port parameter identifies the host computer socket that is

assigned to the marking system. If more than one marking system

is installed in a network configuration, each system must use a

separate and unique port number. The Address parameter identifies

the IP (Internet Protocol) address of the host computer. The

marking system software supports both fixed addressing and

dynamic addressing.

RS-232 Interface. The serial (RS-232) communications interface

is most often used with remote devices such as host computers,

terminals, or bar code scanners. The RS-232 interface supports both

Extended Protocol and Programmable Protocol.

The following describes the serial data character format on all

transmissions to and from the system PC.

• Asynchronous

• 300, 600, 1200, 2400, 4800, 9600, 19200, 38400,

57600, or 115200 Baud

• 1, 1.5, or 2 Stop Bits

• 5, 6, 7, or 8 Data Bits

• None, Even or Odd Parity

I/O Control Signals. The TMC090 is configured for DC I/O only.

The TTL Input port may be used to connect a remote push button

control for sending Start Print and Abort commands to the marker.

The I/O port may be used to connect a PLC or other DC I/O source.

The I/O port allows remote control of printing, aborting, and

monitoring of the Ready and Done output signals. Additionally, the

I/O port allows for remote pattern selection. The marking system

can monitor four separate input signals and, based on the on/off

state of those signals, will select and open a specific pattern stored

on the PC.

Cable connectors and connector pins are supplied with the controller

for constructing appropriate interface cables.

START PRINT Input signal: begin print cycle

SEL_0, 1, 2, 3 Input signals: pattern selection

ABORT Input signal: abort print cycle

INPUT COMM For all inputs (+ or – supply)

READY Output signal: ready for message or start print

DONE Output signal: print cycle complete

OUTPUT COMM For all outputs (+ or – supply)

Host Communications. The marking system software allows you

to configure communication parameters to transmit and receive

data to and from a host computer or a remote I/O device. The host

communicates with the marking system software via the host

interface on the system PC. The software passes information to

and from the marking equipment via the controller USB interface.

To provide maximum integration flexibility, the system software

supports Ethernet (TCP/IP) interfaces and serial (RS-232)

interfaces. It also provides two protocol choices: Programmable

Protocol and Extended Protocol.

Programmable Protocol. Use this protocol where very simple

one-way communications are required (such as with bar code

scanners). Programmable Protocol provides no error checking or

acknowledgment of the transmitted data. Note that XON/XOFF

Protocol applies even when Programmable Protocol is selected.

Starting Character specifies where the software begins to count

character positions. This number must be entered in ASCII

decimal format such as 2 for STX.

Terminating Character identifies the end of transmitted string

(usually ASCII carriage return character, decimal 13).

Character Position counted from the starting character ignoring

all characters preceding it.

Character Length accepts variable length messages (if set to 0)

or messages of a pre-specified, fixed number of characters.

Ignore Character identifies the character to ignore when sent

from the host (usually ASCII line feed character, decimal 10).

Message Type allows message-type recognition which defines

how the marking system will use data it receives from the host.

49 (Type 1) overwrites first text field with data extracted from

the host

80 (Type P) loads a specific pattern identified by data extracted

from host

81 (Type Q) updates text in first query buffer with data extracted

from host

86 (Type V) updates first variable text field with data extracted

from host

0 (Type Zero) indicates that host will provide message type,

field number (if applicable), and data; delegates message

type selection to the host on message-by-message basis. The

host message must use the format

Tnn<string> where:

T = 1, P, Q, or V to indicate the message type.

nn = two-digit number to indicate field number or

query text buffer where data will be placed. Note

that a number is not used with Message Type P.

<string> = field data (Message Types 1, Q, or V) or

pattern name (Message Type P) , as applicable.
