12 6 F 3 B 0 3 5 6 2. Scan transmission overview The Scan transmission method is suitable for real time control data linkage. In the S20LP, data sending station is rotated cyclically. Each station has common memory for Scan transmission. The size of the common memory is 4096 words.
13 6 F 3 B 0 3 5 6 Main terminal station, back-up terminal station and general station When power is applied to each S20LP-station, one station must have station address number 1. The station of station number 1 becomes the main terminal station.
14 6 F 3 B 0 3 5 6 3. Setting for data linkage 3.1 Station number setting Each station should have unique station number. If a station number is duplicated, the S20LP network cannot be established. Allowable station number is 1 to 64. To set the station number, two rotary switches (STNH and STNL) are provided on each station.
15 6 F 3 B 0 3 5 6 (2) Network assignment a) Set "LINK" for the Blocks to be assigned. 0 Receive Block 1 W000-063 LINK Block 2 100 W064-127 LINK Send Block 3 W128-191 LINK Block 4 23.

17 6 F 3 B 0 3 5 6 b) If two S20LP-stations are mounted on the T3H, the station which is allocated closer to the CPU in the I/O allocation (see (1)) is assigned as CH1.
18 6 F 3 B 0 3 5 6 <T-PDS screen example 3>.
19 6 F 3 B 0 3 5 6 c) If two S20LP-stations are mounted on the T3H and multi layers Scan transmission function is used, use the "GLOBAL" setting.
20 6 F 3 B 0 3 5 6 <T-PDS screen example 4> Note) The following rules are applied to the Network assignment. Do not set LINK both for CH1 and CH2 for the same Block. If duplicated, CH1 has priority. In the GLOBAL setting Block, the "receive" side CH data is transferred to the W register and the "send" side CH.
