3.2.3
The EH-150 CPU has two link areas of 1024 words (No.1 LINK and No.2 LINK).
The EH-RMP operates in the EH-150 system as a LINK module. The first EH-RMP in a rack uses No.1 LINK area
and the second EH-RMP uses No.2 LINK area .
For the EH-RMP, specify the output area size of the link ( maximum 256 words).
Top Assign No. is fixed to WL0. (for No.2 LINK is WL1000.)
Last Assign No. is between WL0 and WLFF. (for No.2 LINK is between WL1000 and WL10FF.)
Input area of the link is always fixed from WL200 to WL2FF ( for No.2 LINK is WL1200-WL12FF).
