A1-26 A1.8 Connecting to a Modem n Setting and Sample Program when Connecting to a Modem We describe here how to connect to an external modem and send a message to a beeper. Sending a message to a beeper requires programming in ladder or BASIC. The program writes the telephone number of the beeper and the message to be transmitted to the internal registers of this module, turns on the Dial Request relay to start auto-dialing.
E: Event Transmission Function F3LC12-1F: #1: for port 1/ #2: for port 2 M: Modem Connection Function F3LC11-1F: use only #1. #2 is reserved. (dialing, message transmission) Redialing is not allowed for message transmission to beeper. S: Software setting function Relays not listed in the above table are reserved by the system.
Page 44
E: Event Transmission Function F3LC12-1F: #1: for port 1/ #2: for port 2 M: Modem Connection Function F3LC11-1F: uses only #1. #2 is reserved. (dialing, message transmission) Relays not listed in the above table are reserved for future use. S: Software setting function Do not use reserved relays.
Page 45
Data position numbers in brackets are for BASIC CPU access. For F3LC11-1F, the data size for event or message transmission is 30 words max. For F3LC12-1F, the data size is 127 words max. for each port. Accessing from BASIC Using the PC Link Module with the personal computer link function to access the common area of a BASIC CPU module does not require creation of a program on the BASIC CPU.

A2-3 n Devices (Sequence CPU and BASIC CPU) The device names that can be used in PC link commands are given below. In ladder programs, present values of timers and time-up relays are represented the same way as in T0001. However, in PC link commands, they are represented differently, as in TP00001 and TU00001.
BASIC language, etc. uses CR (or CR+LF) for end identification. When connecting to these types of higher-level equipment, you should set the ending character to “Yes”. Append an ending character when connecting to TOP series from Yokogawa. IM 34M6H41-02E 2nd Edition : Aug. 1, 2005-00...
A2-5 n Formats of Access Commands/Responses Only uppercase alphabetic characters A-Z (ASCII codes $41-$5A) can be used in commands and responses. Format of Commands (Higher-level equipment→FA-M3 (PC Link Module)) Command response, parameters FA20001.VSD (1) STX The STX character (control code) identifies the beginning of text. Its ASCII code is “$02”...

If communications is normal Command response FA20003.VSD If communications is successful, the character string “OK”...
A2-8 n Checksum Calculation The checksum is obtained by simply summing the ASCII codes of the character portion of a command or response. We show below how the checksum is calculated on the sending end (command). Add the ASCII codes of characters, starting with the character following the STX character (that is, the first character of the station number) until the character preceding the checksum (that is, the last character of the command parameters).
A2-9 n List of Error Codes in Response When a communications error or a command error occurs, or when the CPU module of the FA-M3 returns an error, the character string “ER” and two error codes (2 hexadecimal characters, EC1 and EC2) are returned. EC1: Error code (See Table A2.8) EC2: Detailed error code...
Page 58
A2-10 The Detailed Error Code (EC2) is valid when the Error Code (EC1) is equal to $03, $04, $05, $08, $41, $51 or $52. It is invalid otherwise. In the case of a parameter error, the number of the parameter where the error has occurred is stored in the Detailed Error Code.
A3-1 A3. Modem Connection Function You can connect an external modem to this module and then use PC link commands to monitor devices on the remote FA-M3 via the modem. Moreover, an on-site alarm can be generated and transmitted from the FA-M3 to the higher-level equipment or transmitted to a beeper.

B1-1 Overview The Personal Computer Link Module (F3LC11-2F) uses serial communication (RS- 422/485) to exchange data with higher-level equipment (displays, personal computers, DCS, etc.). Installing this module in the FA-M3 and connecting it to a higher-level equipment such as a display or a personal computer enables you to monitor the operating statuses of the FA-M3 and FA-M3 devices, as well as perform setup from the higher-level equipment.
Personal Computer Link module returns a reply (response). Compact Field Server from Yokogawa Electric Corporation. It enables real-time monitoring of field data of the FA-M3 from a WWW browser or in an Internet environment, using the Webmetry field monitoring package.
B1-3 Event Transmission Function You can send any data that is 30 words or shorter from the FA-M3 to a higher-level equipment. Event transmission requires some programming on the FA-M3 side. (You can send an event by simply storing the data to be transmitted into the register of the Personal Computer Link module and then turning on the Request to Send relay).

B2-3 Devices (Sequence CPU and BASIC CPU) The device names that can be used in PC link commands are given below. In ladder programs, present values of timers and time-up relays are represented the same way as in T0001. However, in PC link commands, they are represented differently, as in TP00001 and TU00001.
BASIC language, etc. uses CR (or CR+LF) for end identification. When connecting to these types of higher-level equipment, you should set the ending character to “Yes”. Append an ending character when connecting to TOP series from Yokogawa. IM 34M6H41-02E 2nd Edition : Aug. 1, 2005-00...

We show below how the checksum is calculated on the sending end (command). Add the ASCII codes of characters, starting with the character following the STX character (that is, the first character of the station number) until the character preceding the checksum (that is, the last character of the command parameters).
B2-9 List of Error Codes in Response When a communications error or a command error occurs, or when the CPU module of the FA-M3 returns an error, the character string “ER” and two error codes (2 hexadecimal characters, EC1 and EC2) are returned.

Data format and transmission speed can be changed even after the Personal Computer Link module is mounted to the base unit.
B4-2 Operation of the Software Setting Function Set the data format and transmission speed using the following procedure. Write the setting values to data position numbers 38 and 39 using the WRITE instruction. Turn on output relay Ylmm35 (Setup Request) using the SET P instruction.

C1-1 C1. Overview The FA-M3 Personal Computer Link Module (F3LC11-1N) has an RS-232-C communication port. The F3LC11-2N also has an RS-422-A/RS-485 communication port. The RS-232-C port enables communication with a higher-level computer such as a personal computer, or a display with a PC interface on a one-to-one basis. The RS-422-A port allows a maximum of 10 FA-M3 modules to be connected, and the RS-485 port allows up to 32 modules to be connected.

C4-6 (7) Checksum Checksum can be added for data checking. You can select whether to add the checksum by using the Data Format Setting switch (Refer to Figures C2.4 and C3.4) at the back of this module. If the checksum is enabled, a ‘checksum’ must be ap- pended to a command when it is transmitted from the higher level computer (or dis- play) to the FA-M3.
C4-7 Response Format and its Elements The format of a response that is sent back from the FA-M3 to a higher level computer (or display) is shown here. For the meaning of each element, refer to item [1], “Command format and its elements.” For more details, see the “Personal Computer Link Commands” manual (IM34M6P41-01E).
