SPECIFICATIONS - MODEL X120 MULTIPLEXER/TERMINATION UNIT

Features

• Monitors up t o 48 switching devices

• Reliable high-speed event transmission

• Interfaces with most plant computers and the Ronan Model X110 Serial Input Visual Annunciator

• Internal relay for self-test and power supply status

• Digital filtering to assure accurate monitoring of status changes

• Up to 32 units may be series connected to monitor up to 1,536 total inputs

• Considerable savings in cable costs by the use of serial transmission

General Description

The Ronan Model X120 Multiplexer/Termination Unit is designed to continuously monitor up to 48 field contacts and/or solid state switching devices. Any input status change is converted to serial data which can be transferred to a plant computer or serial input display device, like Ronan’s Model X110 visual annunciator. The input signals are monitored using optoisolated input circuits to provide isolation between input signal voltages and the Model X120 logic circuits. The 48 inputs are sequentially scanned on a continuous basis.

Input status changes are digitally filtered for a 16 millisecond period before being transmitted over the high speed serial line. Self-test and watchdog timer circuits, in addition to power supply monitor circuits, are displayed by means of LED indicators. Loss of a power supply voltage will de-energize the self-test relay.

Up to 32 Model X120 units can be daisy-chained to form a single serial output which monitors the status of up to 1,536 field contacts or solid state switching devices.

Each Model X120 unit receives 5 VDC power to operate its internal logic. An isolated 125 VDC or 24 VDC voltage source can be used to power the field contacts. The isolated power source, along with digital filtering, assures maximum noise immunity for system operation.

1.0 MULTIPLEXER CONTROLLER MODULE X120-1000

The primary function of the controller board is to gather “event” data from 48 input channels and relay the collected information to the Model X110 via RS422/485. This is done by continuous scanning of each of the eight inputs with U7 (1-OF-8 DECODER/DEMULTIPLEXER). There are 8 outputs from U7 (CS0, CS1, CS2, CS3, CS4, CS5, CS6, CS7) which are used to scan all the channels and to read the status of SW2 and SW3. The function

and the logical address of each output is shown in Figure 1.

Figure 1

Each time the controller board scans all the input channels, it stores all the data in the internal memory and makes filter calculations (refer to filtering section for more information). After filter processing, all the status changes of inputs are transferred to the transmit buffer and ready to be transmitted. If the old status change of any input has not been transmitted from the transmit buffer before the status of the same input changes, the controller board would not register the new status change of that input channel. Therefore the old status of input channels would not be lost before being transmitted to the X110 system.

2.0 DATA FORMAT AND PROTOCOL

All the data from the X120 is transmitted serially via RS232 (P1) to a terminal/printer and RS422/485 (P2) to X110.

2.1 Data Transmission Format

Baudrate = 1200 / 9600 Number of data bits = 7 Number of stop bits = 1 Parity = Even

2.2 Status Format

Six bytes of data would be transmitted each time the status of any input channel changes. The formats of these data bytes are shown below:

2.3 Protocol

The protocol between X120 and X110 is RONAN proprietary and is done to make sure that any status data transmitted from the X120 would be received by the X110 properly. Each time the X120 transmits a status change of an input, it will wait for approximately 250ms to receive an ACK (Ctr F) from the X110 which means that the X110 received the data without any error. If after 250ms the ACK is not received, the same status would be transmitted again up to three times. After the third time, the transmit error LED

would be illuminated and the horn relay would be activated before sending the next status change.

Note: When an ACK is received by the X120, the transmit error LED would be turned off (if it was

on) and the horn relay would be deactivated.

3.0 SPECIAL FUNCTIONS

Along with its event collecting/transmitting tasks, the controller board performs a number of secondary tasks that are explained in different sections.

3.1 Filtering

Page 3 of 12

Before reporting the occurrence of an “event”, the controller board’s program makes “software filter” calculation. Recall, that a change in the status of a contact must be seen for a specified duration of time equal to the “time constant value”) before an event is actually declared. The filter calculations are made to determine when the proper duration of time has expired. The “time constant value” is set to 16ms for all the input channels.

3.2 Input Channel Test

The controller board tests all the 48 input channels of the multiplexer for alarm and return to normal conditions (only if SW2-7 is set to the ON position) each time it is reset. The test error LED would be illuminated and the horn relay would be made active if any of the 48 input channels failed to test. This test is done by using two relays K1 and K2. The K1 relay is used to disconnect the field contact power to all the inputs. The K2 relay is used to test all the input channels by connecting and disconnecting the field contact voltage to all the channels and checking all the outputs for proper function. The test error flag would be set on each channel that was bad and they will be reported before the alarm summary (refer to ALARM SUMMARY section for more information) with the following format:

The BAD channel report is very useful for troubleshooting input boards. By connecting a terminal to RS232 (P1) port, all the bad channels (if there is any) would be displayed before the alarm summary each time the X120 is reset.

Note: The input channel test is valid only if all 48 inputs are set for dry co ntact (B&C jumpers installed).

3.3 Alarm Summary

To update all the annunciator windows with the current status of inputs, Alarm Summary of all the input channels (open or closed) would be reported if the X120 is reset. To clear all the annunciator windows before alarm summary, the following data would be sent:

Note: All the data is sent with even parity.

Page 4 of 12

After clearing all the windows, all the bad input channels would be reported (if there is any) only if SW2-7 was set to the ON position. The alarm summary would be reported next, followed by this data:

4.0 CONFIGURATIONS

The X120 multiplexers can be connected to the X110 system in two different ways (parallel & serial) and J2, J3, J4, J5 burg jumpers have to be set differently for each X120 in different configurations.

4.1 Parallel Configuration

Only one X120 is connected to the X110(s) in this configuration and J2, J3, J4 and J5 burg jumpers are used (installed).

4.2 Serial Configuration

Two to thirty-two X120s can be connected together serially in this configuration. Only J2 & J3 on the first X120 and J4 & J5 on the last X120 are installed. J2, J3, J4 and J5 should not be installed on any X120 between first and last.

Figure 2 shows how the X120s are connected serially.

5.0 LED INDICATIONS

There are three LEDs on the controller board that indicate the status of the X120s and communication between X120s and X110s. The operations of these LEDs are explained in the following sections.

5.1 Test Error LED (Red)

Refer to section 3.2.

5.2 Transmit Error LED (Red)

Refer to section 2.3.

5.3 Status/Run LED (Green)

The run/status LED indicates the connection between all the X120 multiplexers. All the run/status LEDs should be flashing synchronously if connections between all the X120s are okay. The flashing rate depends on the number of X120 multiplexers connected together and decreases by connecting more X120(s) in the chain.

Note 1: If any of the X120 multiplexers is transmitting events, the run/status LEDs stop flashing

during the transmission time and stay on or off depending on its state which transmission started.

Note 2: Make sure that all the burg jumpers (J2, J3, J4, J5) are installed properly.

6.0 JUMPER SETTINGS

6.1 J2, J3, J4, J5

Refer to section 4.0.

6.2 J6 Jumper

The DS1232 (U9) provides a watchdog timer function by forcing RST and RST signals to the active state when the ST input is not simulated for a predetermined time. The time period is set by the TD input to be 150 ms with TD connected to ground (J6-2&3 installed), 600 ms with TD left unconnected (J6 not installed), and 1.2 seconds with TD connected to Vcc (J6-1&2 installed).

6.3 J7 Jumper

This jumper is for setting the horn relay contact to normally open or normally closed. The horn relay is normally energized. To set the horn relay output contact, install (J7-1&2) for normally open and (J7-2&3)

for normally closed.

The factory setting is (J6-1&2 installed)

The factory setting is normally open (J7 -1&2 installed)

6.4 J8, J9 Jumpers

These jumpers are to enable/disable the data transmission to test port (P1). P1 port is used for testing the X120 boards and can be connected to any terminal with the RS232 port to display the ASCII data

transmitted by the X120 to the X110.

Install J8 & J9 to enable and remove J8 & J9 to disable the data transmission from the X120 to RS232 test

port P1.

Note: The J8 & J9 are installed only on the master controller board to test the system.

6.5 J10, J11 Jumpers

These jumpers are to enable/disable the data reception from RS232 test port (P1) and they are used only for testing the system.

The factory setting (J8&J9 installed)

The factory setting is (J10&J11 installed)

Note: If you install J10 & J11 for testing the system, disconnect the cable between the X120 and

X110.

6.6 J12, J13 Jumpers

Installing a burg jumper on J12 will place in service a 112 ohm line-to-line terminator across the receiver line (RXD, RXD RTN). If the system is subject to extremely noisy environments, it would be better to terminate only the receiver side of the communication line by line-to-ground termination on each side of the receiver line (RXC, RXD RTN). Installing burg jumpers on both J12 and J13 will terminate each side

of the receiver line through 56 ohm to ground .

6.7 J14, J15 Jumpers

Installing a burg jumper on J14 will place in service a 112 ohm line-to-line terminator across the receiver line (TXC, TXC RTN). Installing burg jumpers on both J14 and J15 will terminate each side of the transmitter line through 56 ohm to gro und.

7.0 SWITCH SETTINGS

Position 1 to 5 of SW2 are for setting the MUX numbers and they are set as follows:

MUX NUMBER SW2-5 SW2-4 SW2-3 SW2-2 SW2-1

MUX 01 OFF OFF OFF OFF OFF MUX 02 OFF OFF OFF OFF ON MUX 03 OFF OFF OFF ON OFF MUX 04 OFF OFF OFF ON ON MUX 05 OFF OFF ON OFF OFF MUX 06 OFF OFF ON OFF ON MUX 07 OFF OFF ON ON OFF MUX 08 OFF OFF ON ON ON MUX 09 OFF ON OFF OFF OFF MUX 10 OFF ON OFF OFF ON MUX 11 OFF ON OFF ON OFF MUX 12 OFF ON OFF ON ON MUX 13 OFF ON ON OFF OFF MUX 14 OFF ON ON OFF ON MUX 15 OFF ON ON ON OFF MUX 16 OFF ON O N ON ON MUX 17 ON OFF OFF OFF OFF MUX 18 ON OFF OFF OFF ON MUX 19 ON OFF OFF ON OFF MUX 20 ON OFF OFF ON ON MUX 21 ON OFF ON OFF OFF MUX 22 ON OFF ON OFF ON MUX 23 ON OFF ON ON OFF MUX 24 ON OFF ON ON ON MUX 25 ON ON OFF OFF OFF MUX 26 ON ON OFF OFF ON MUX 27 ON ON OFF ON OFF MUX 28 ON ON OFF ON ON MUX 29 ON ON ON OFF OFF MUX 30 ON ON ON OFF ON MUX 31 ON ON ON ON OFF MUX 32 ON ON ON ON ON
