I did a quick search and didn't see what I was looking for, so here goes. I suppose this might fall into the "other PLC" category, but please bear with me for the Modicon tie-in... We inherited a system with Motorola MOSCAD and ACE3600 RTUs, both of which convert their native MDLC protocol to Modbus at a communication port. We need to hook up some simple Maple Silver series (HMI520T) 6" operator displays for basic discrete and analog status displays. I don't know if the addressing is strictly MOSCAD related, or if it's generic to any Modbus protocol. A conversion formula is used to convert MOSCAD table/column/row to Modbus address: Modbus = (Table * 2048) + (Column * 256) + Row + 1 I realize that this formula is for relative addressing, and that for absolute 5-digits we'd probably need to add 30,000 (or 40,000?). I noticed on the Maple product, they only support Moscad tables 0 through 4. If my integer values are stored in Table 1, then the converted Modbus address is typically 20xx (for example 2045). However on the Maple display, for analog/integer values, the addressing formats are typically "3x" and "4x", which I think refer to 30,000 addresses for analog inputs, and 40,000 addresses for holding registers. Other listed formats include LW, RWI, RW, Ms_RW or Ms_LW. Any advice on which is intended to match our 20xx address? Also - we're using some Table 1 words to transfer blocks of discretes. So the address would still be 20xx, but with a decimal or colon used to denote individual bits (for example, 2044.3). The Maple software's discrete graphic dialog box suggests data formats LB, 1x, 0x, RBI, RB, Ms_RB, Ms_LB. Any advice on which would match our intended use? Perhaps this question is too specific to the Maple units, in which case I wouldn't mind a referral to another forum where folks might know the product. I called Maple tech support and the guy said he didn't know a thing about MOSCAD or Modicon addressing and to just read the manual (and get off the phone). Thanks...

We inherited a SCADA system which uses Motorola MOSCAD-L hardware for RTU/store & forward operations. It uses "Toolbox" software for configuration and logic programing. Toolbox version 8.50, which runs on Windows 2000, supports up to 41 zones on a radio link. For example, radio links 1/1 through 1/41. Toolbox version 9.50, which we use on our WinXP laptop for configuration, only supports 9 zones on a radio link. For example, 1/1 through 1/9. It poses a problem when the field system operates on many zones but the software only supports the first 9 zones. Can someone explain to me why Motorola appears to have migrated their product by reducing the capabilities of the radio network? Is there a support number at Motorola that will assist users of their products whose support contract has long since expired?
