DESCRIPTIONS ■ RUN Output (LED) Operation Input unit The LED for the Input Units (A1, A2, A4, G3, G4 and P4) turns ON when the network is on-line. When there is an abnormality in the network, the LED turns OFF. The network is reconfigured after an abnormality. Output unit The LED for the Output Units (C1, C2, C7, C8, M3, M4 and U4) turns ON when the network is on-line and the unit receives data from the corresponding Input Unit. When there is an abnormality in the network or there is no data receiving, the LED turns OFF. When the I/O Units are connected via the 22LS1 (DLS), once the LED turns ON, it remains ON regardless of the state of Input Unit or the leased circuit. When the Output Unit is connected to the DLC (for setting data from the DLC), the LED turns ON once the Output Unit receives normal data, and remains ON even when there is no data update. I/O Unit The LED's operating conditions for the I/O Unit (E5 and E6) are combined ones of Input Unit and Output Unit. Caution: When the network is reconfigured e.g. by noise interference, the RUN LED and output for all units on the network turn briefly OFF until they are turned ON after the reconfiguration is complete. ■ Station Number (Address) A) 1 input unit and X output units: Match the address for input and output modules. The input data can be output at several modules. B) I/O mixed modules: Set an even number and a consecutive number for the 2 corresponding modules.

MODEL: 22LA1 http://www.m-system.co.jp/ 22LA1 SPECIFICATIONS ES-6554 Rev.8 Page 3/22 C) Computer interface: Set address numbers to correspond with the computer as I/O module. ■ Transmission Time Integrate all the transmission time for each process input (or I/O-mixed) module in the system.

  • Contact input, BCD, 16 points (A2) 1.5 msec.
  • Contact input 8 points (A4) 1.5 msec.
  • Contact I/O each 4 points (E5, E6) 1.5 msec.
  • Analog input 8 points (G3) 12.0 msec.
  • Analog input 4 points (G4) 6.0 msec.
  • Pulse input 4 points (P4) 6.0 msec. An analog module does not transmit all its signals in serial but does 1 point per each cycle. For example, when 1 contact input module (8 points) and 1 analog input module (4 points) are connected, 8 point contact signal and 1 point analog signal are transmitted in turn. One cycle time is therefore calculated as: 4 points × 1.5 msec. + 6 msec. = 12 msec. This method is beneficial for giving a priority to contact signals which vary rapidly. ■ Transmission line configuration The multi-drop transmission line containing 22LA1 and DLx units should meet the following conditions. Contact M-System's sales office or representatives when designing. A) 10 kilometers at maximum in total system. B) Line consists only of 22LA1 modules : one multitransmission line can contain at the maximum of 16 units within the total C) 22LA1 modules plus link adapter (model: DAL4) : DAL4 units can expand the total distance. (8 DAL4 units max.) D) 22LA1 modules plus DL x units : the total distance of a section consists of 22LA1 modules is less than 500 meters. The 22LA1

1 A L 2 21 A L 2 2

modules can be connected to DLx units via a DLx-7 unit. (Eight DLx-7 units max.) distance of 500 m.
