DESCRIPTIONS RUN Contact (LED) Behaviors The LED operates when both the communication line conditions and DLS units conditions are true. Comm. line conditions Input units (00, A, A, G and P): The LED turns ON with the network configured; OFF in an abnormality; the network is reconfigured after an abnormality. Output units (C, C, C, C, M and U): The LED turns ON when data from the paired input unit is received normally, with the network configured; OFF when the data is lost; turns also OFF in an abnormality in the network. I/O-mixed units (E, E, R and S): Functions of both input and output units are used. DLS units conditions: The LED turns ON when the transmission is normal between the DLS units; OFF after three retries in a transmission abnormality. [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. How to Caculate Transmission Speed. Data Volume and Transmission Time of I/O Unit I/O type of DLS (or DLA) units determines each unit's multi-transmission time. The DLS collects data from each station and transmits to the other station. (Input Model Suffix: Data Volume) A, E: 0 bytes A: 0 bytes G, P: bytes R: bytes S: bytes C, C, C, C, M, U: 0 bytes Transmission time for unit is calculated utilizing each unit's data volume. Transmission time = (data volume) (number of data bits per byte transmission speed [bps]) + waiting time per unit (0. sec.) [example] Transmission time of type A, S and C units A unit (00 bps) 0 00 + 0. = 0. (sec.) S unit (00 bps) 00 + 0. =. (sec.) C unit 0 sec. Transmission time for those units with 0 data volume equals 0.. Start / End of Transmission The DLS transmits codes to the paired station at the start and end of transmission sequence respectively. The data volume differs according to modem type. (Modem Type: MOD/; Others) Start-of-transmission time: bytes; bytes End-of transmission time: bytes; bytes Start-of-Transmission time = (data volume) (number of data bits per byte transmission speed [bps]) + waiting time per unit (0. sec.) Remark: Waiting time for MOD and MOD is 0. sec. [example] Modem type /MA (00 bps) 00 + 0. = 0. (sec.) End-of-Transmission time = (data volume) (number of data bits per byte transmission speed [bps]) + waiting time per http://www.m-system.co.jp/ DLS SPECIFICATIONS ES- Rev. Page /0

unit (0. sec.) [example] Modem type /MA (00 bps) 00 + 0. = 0. (sec.). Total Transmission Time per Unit The above () transmission time and () & () Start-/End-of transmission time must be added to calculate the total transmission time required by one DLS unit. Total transmission time per unit = (start-of-transmission time) + (transmission time) + (end-of-transmission time) [example] Station A: S and A units Station B: S and C units Modem type /MA (00 bps) Station A transmission time 0. + (. + 0.) + 0. =. (sec.) Station B transmission time 0. + (. + 0) + 0. =. (sec.). Overall Transmission Cycle The overall transmission cycle is determined as the time required by one DLS unit starting transmission before the next transmission. Overall transmission cycle = Station A total transmission time + Station B total transmission time [example] Station A: S and A units Station B: S and C units Modem type /MA (00 bps). +. =. (sec.) The time required for the input signals to be output at the output unit varies according to the exact moment of input. Minimum (Station A input to Station B output) = Station A total transmission time per unit =. (sec.) Maximum (Station A input ot Station B output) = Overall transmission cycle + Station A total tansmission time per unit =.0 (sec.) Therefore, the time required for a Station A input to be output at the Station B varies between. and.0 seconds as far as there is no transmission error. http://www.m-system.co.jp/ DLS SPECIFICATIONS ES- Rev.

SYSTEM CONFIGURATION EXAMPLE multi-transmission line RS--C (straight) MOD DLA-A-K (station address SA = 0, SA = ) DLS-SAB-K/MA (station address SA = 0, SA = ) process I/O process I/O leased circuit multi-transmission line MOD RS--C (straight) process I/O DLS-SAB-K/MB (station address SA = 0, SA = ) process I/O DLA-C-K (station address SA = 0, SA = ) HOW TO SET STATION ADDRESSES The I/O units are connected in a series via a couple of modems. Set the station address to DLA units as described in the DLA data sheet. For the DLS with no process I/O, set a number remote from those for DLAs (such like FF, FE). When the DLS has process input or output, set it the same way as the DLA. HOW TO CONFIGURE MULTI-TRANSMISSION LINE Refer to the data sheet for DLA unit. http://www.m-system.co.jp/ DLS SPECIFICATIONS ES- Rev. Page /0
