Read Block The standard Read block is made up of the following sections: status, rate, load, speed, total, relay status, DI status, multispan, PID, batch, batch prewarn, SPA, Word order. If any of these sections is ‘turned off’ by setting the corresponding part of P762 to a zero, the new map will shift down accordingly and the size will be reduced by that amount, for the Read block. Multiply the parameter value by the memory size, then add up the results to get the total.
