    (PC00) Slave station (PC01) Ｔ Note: Data exchange time between a PC and the JW-21MN can be obtained by the following formula: When the control module is JW-31CUH1/32CUH1/33CUH1/33CUH2/33CUH3, 0.5 ms + 0.5μs x number of bytes to transfer. (When the number of bytes to transfer is maximum (2304 bytes), 0.5 ms + 0.5μs x 2304 = 1.65 ms)

    16-4 Special functions unique to the JW-21MN The functions below are not covered by the ME-NET specifications. They can only be used with PCs which are equipped with a JW-21MN, ME-NET module JW-20MN or ZW-20CM2. (1) Remote programming and remote monitor This paragraph describes the operation procedure of any other station's PC which is connected on the ME-NET.
  • Page 109 — 1 n + 1 n + 2 * The JW-21MN is unusable as a junction station ("n + ME-NET 2" station and "m" station in the figure above). Use JW30H (JW-21MN), JW50H/70H/100H (JW-21MN). Writing data (change program) during operation of the PC is not available for hazard prevention reasons.
  • Page 110 - Network setting Select whether the target station for remote programming or remote monitor is on the standard network connection or on the extension network connection. In the case below, 10 to 12 are standard network connections. 01 to 03 network connections.
  • Page 111 (2) Parameter setting by remote function This paragraph describes how to set the parameters of other stations' network module (JW-21MN/ JW-20MN) connected on the ME-NET. This is only available when the target station is within the standard network connection. Usable support tools are JW-14PG/13PG/12PG.
