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. The station of station number 2 becomes back-up terminal station. Normally stations, except station number 1, become the general stations. The main terminal station controls total timing of the S20LP network. If main terminal station is down, back-up terminal station (station number 2) becomes main terminal station on condition that the back-up enable flag is ON. If the back-up enable flag is OFF, back-up terminal is general station. If both the station of station number 1 and 2 is down, all stations become general station.

To be effective back-up terminal station, the address (1F44H) on the S20LP dual port memory must be set ON. To set the S20LP dual port memory, use the write instruction. Detailed information of write instruction see “T-series Instruction Set (Ladder, SFC)” (UM-TS03***- E004).

Setting the "data send block" (by S-LS)

On each station, the "data send block" is prespecified by using the S-LS. This setting is made by entering the starting addess and the size (number of send words). On a station, up to two "data send blocks" can be specified. (see Section 3.3)

I/O allocation and network assignment (by T-PDS)

On each T2N/T3H, the I/O allocation for S20LP-station and the network assignment are necessary. By using the T-PDS's I/O allocation function, allocate the S20LP-station as "TL-S" (T3H) or E/S (T2N). And by using the T-PDS's Network assignment function, assign (set "LINK" or "GLOBAL") the Link registers (W) to the S20LP-station's common memory (from 0 to 2048), Block by Block. (see Section 3.2)

T2N/T3H accesses the common memory only for the assigned Blocks. (This "Block" and S20LP's "Data send block" are different.)

"LINK" is normal assignment setting. "GLOBAL" is the setting for multi layers Scan transmission. (effective only in T3H)
